General Safety Precautions

WARNING. Systemic hypothermia risks. Systemic hypothermia may cause cardiac arrhythmia, patient shivering, or other system or organ complications. Systemic hypothermia should only be utilized under the supervision of a qualified physician. When treating a patient with the console, appropriately qualified medical staff must routinely and closely monitor the patient and must comply with the following procedures:

• Audible and visual alarms generated by the console require the authorized individual to remain in close proximity to the patient throughout the procedure.
• Always verify the function of the console prior to insertion of an IVTM catheter. In the event of a malfunction, have other means of cooling available.
• When combining the use of the system and other adjunctive means of cooling, ensure that close observation of the patient is maintained.
• Do not use the system in conjunction with other temperature maintenance devices that have an automatic temperature controller. Temperature oscillations may occur that are dangerous to the patient.
• Performance of installation, operation, or maintenance procedures other than those described in this manual may create hazards and may cause the manufacturer’s warranty to become void.
• Sterile components are designed for a single use only. If unauthorized disposable components are used, proper operation cannot be guaranteed and harm to the patient may result.
• Proper aseptic technique must be used while making all sterile connections to the system.
• Never operate damaged or leaking equipment.
• Never operate the equipment without coolant fluid in the coolant well.
• Never use pure water, pure propylene glycol, or alcohol as a coolant fluid.
• Never operate the equipment while smoking or in the presence of open flame.
• Avoid touching the patient simultaneously with metal parts in the console.
• The ZOLL Coolgard and Thermogard consoles are MR Unsafe and, thus, these consoles are not allowed in the MR system room. Therefore, the catheter must be disconnected from the console prior to moving the patient into the MR system room.
  WARNING. Projectile hazard.
  WARNING. Electric shock risk during cardiac defibrillator discharge. The console’s protection against the effect of the discharge of a cardiac defibrillator is partially in the patient temperature probe. To prevent potential hazards to the patient or operator, the console must be used in conjunction with the approved patient temperature probes listed in Specifications section of this manual.

Field strengths from fixed RF transmitters, as determined by electromagnetic site

survey,1 should be less than the compli-

ance level in each frequency range.2 Interference may occur in the vicinity of equipment marked with the following symbol:

Note 1. At 80 Mhz and at 800 MHz, the higher frequency range applies.

Note 2. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorp- tion and reflection from structures, objects, and people.
Note 3. The frequency range between 100-150 kHz is associated with interference from low frequency RFID equipment.
Note 4. The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz tested are 6.765 MHz to 6.975 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
Note 5. Tested for immunity to RF interference from transmitters operating at 125 kHz, 134.2 kHz and in the frequency ranges between 3.155 MHz to 3.4 MHz and between 7.4 MHz to 8.8 MHz.

1. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcasts and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the console is used exceeds the applicable RF compliance level above, the console should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the console. 2. Unless otherwise noted, over the frequency ranges 150 kHz to 80 Mhz, field strength should be less than 10 V/m.

Note. The following degradation associated with essential performance are not allowed during testing: component failure, changes in programmable parameters, resets to factory defaults, changes in operating modes, false alarms, cessation or interruption of any intended operation, even if accompanied by an alarm, initiation of any unintended operation, including unintended or uncontrolled motion, even if accompanied by an alarm, error of a displayed numerical value sufficiently large to affect diagnosis or treatment, noise on a signal in which the noise is indistinguishable from physiologically-produced signals or the noise interferes with interpretation of physiologically-produced signals. The Thermogard XP console is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. You can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the console as recommended below, according to the maximum output power of the communications equipment.
Table 1.3. Recommended separation distances between portable and mobile RF communications equipment and the console.

Transportation, Shipping and Storage Conditions
When shipping or storing the console, follow these recommendations:

• Do not allow liquids to spill on the console or its packaging.

• Keep in a cool, dry place.

• Fragile contents, handle with care.

• Always handle and store with the top facing up.
  When transporting the console around the hospital, follow these recommendations:

• Move the console by the handle only; do not push or pull on the display head.

• Request assistance from another person to lift the front wheels of the console when moving it over a threshold. Use handle to gently pull unit over the obstacle while your assistant stabilizes the front of the unit.
  WARNING. Tipping hazard. The console may tilt in case of transport outside its crate and over a threshold.

Ignition of Flammable Anesthetic Mixtures
The console is not category AP or APG equipment and must not be used in oxygen-rich environments or environments where flammable anesthetic gas mixtures are present. Electrical Hazards This equipment has been tested and found to comply with the EMC limits of the international standard IEC 60601-1-2. These limits are designed to provide reasonable protection against interference in a typical medical installation. The equipment can radiate radio frequency energy if not installed in accordance with the instructions, and may cause harmful interference to other devices in the vicinity. There is no guarantee that interference will not occur in a particular installation. Always comply with the following:

• To avoid the risk of electrical shock, do not remove any panels of the product.
• Refer servicing to qualified personnel.
• Never operate equipment with damaged power line cords. The Thermogard XP requires special precautions regarding EMC and needs to be installed and put into service according to EMC information provided in this manual. Portable and mobile RF communications equipment can affect the Thermogard XP.

Caution. Dangerous Voltage. Electric shock hazard. Always turn off the console and disconnect the power line cord from the source before performing any service or maintenance procedures, or before moving the console.To avoid the risk of electric shock, this equipment must be connected to a supply mains with protective earth. WARNING. The potential equalization conductor should be connected to the potential equalization bus bar of the electrical installation when available. Refer to the requirements in the IEC 60601-1 standard.
Primary Patient Temperature Probe (T1) Failure
The console relies upon the patient temperature reading from an YSI-400 type thermistor connected to the primary patient temperature probe (T1). There are rare failures of this type of thermistor that cannot be detected by the console with 100% reliability.
Failure of the T1 can result in either patient hypo- or hyper- thermia. Death or serious injury to the patient may result. A secondary patient temperature probe (T2) connection is therefore built into the console. For patient safety, either use both the T1 and T2 connections or employ the T1 probe with an independent frequent check of patient core temperature.
WARNING. Never clinically use a resistor in place of the T1 temperature probe. ZOLL supplies fixed value resistors and variable resistor test boxes (e.g the TP-400 FOGG Box) for testing, training and demonstration pur- poses. These can be plugged into the primary patient temperature probe T1 connection on the front of the console to represent a patient. Never use this device, or other method, to circumvent the normal patient temperature feedback control when the console is connected to the patient. Doing so exposes the patient to the hazards associated with hypo- or hyper- thermia. Death or serious injury may result.
Configuration Changes
WARNING. No modification of this equipment is allowed.
Caution. Certification requirements for external equipment connected to the console interfaces. Equipment connected to the analog and digital interfaces must be certified to the respective IEC standards (i.e., IEC 60950 for data processing equipment and IEC 60601-1 for medical equipment). Furthermore, all configurations shall comply with the system standard IEC 60601-1. Any person who connects additional equipment to the signal input part or the signal output part configures a medical system and is therefore responsible that the system complies with the requirements of the system standard IEC 60601-1. Priming the Saline Circuit WARNING. Do not prime the saline circuit while connected to a patient. During the priming operation, the airtrap alarm will be disabled. Air present in the saline line may be circulated through the indwelling catheter. Before priming the circuit or during troubleshooting for possible leak, disconnect the heat exchange catheter, then connect the IN and OUT Luers of the saline circuit together.
Air Entry Into the Tubing Circuit
Air entry may occur with the failure of any part of the Start-Up Kit, between the saline bag and the outflow of the pump. In such cases, the integrity of the catheter prevents air entry into the patient. In the rare event of a second, simultaneous failure of the catheter, air entry into the patient is possible. Air entry into the tubing circuit will usually, but not always, be associated with an air trap alarm that will stop the console. Always investigate air trap alarms. The cooling circuit is a closed loop–usually air trap alarms indicate a breach somewhere in this closed loop (occasionally an air trap alarm can be caused by condensation forming on the air trap exterior). With any air trap alarm, check both the integrity of the catheter and the Start-Up Kit (see below). Periodically check the Start-Up Kit for significant air bubbles and replace the kit if necessary.
Intraluminal or balloon leakage
WARNING. Intraluminal leakage (between the saline lumen and infusion lumens) or balloon leakage is a potential catheter failure mode. In the event of such a failure, sterile saline from the cooling circuit is introduced into the patient. Intraluminal leakage or balloon leakage is typically associated with a fluid loss alarm once the saline bag has been depleted and stops the system. ^äï~óë=áåîÉëíáÖ~íÉ=ÑäìáÇ=äÉîÉä=~ä~êãëK The cooling circuit is a closed loop system – usually fluid loss alarms indicate a breach somewhere in this closed loop. With any fluid loss alarm, check both the integrity of the catheter and the Start-Up Kit (see below).
WARNING. If you notice a depleted saline bag or an air trap alarm, do not replace the saline bag prior to identifying the location of the leak and taking the appropriate mitigation. Check for system leaks according to the instructions in the Check for a Start-Up Kit leak and Check for a catheter leak sections below. (Note that a leak could be external or internal.) Replacing the saline bag repeatedly without investigating the leak or loss of saline may result in unintended infusion of saline into the patient. Saline infusion may lead to the following adverse effects: local swelling that can cause subsequent local tissue damage; systemic fluid overload that can lead to dependent edema and subsequent skin breakdown; internal organ fluid overload, with subsequent overloading of the brain, lungs or heart. In some cases, this fluid overload may lead to life threatening events. Caution. The console emits an alarm when the saline bag is empty. The bag must be completely empty and additional saline must have drained between the saline spike and the air trap for the saline level in the air trap to drop sufficiently to trigger the alarm.

Check for a Start-Up Kit leak

1. Check the air trap for condensation. If the air trap shows signs of condensation, wipe the air trap and reinstall it in the console. In the case of an air trap alarm, verify that the air trap alarm is cleared after this step.
2. Carefully check the saline path from the saline bag to the console for any leaks. Check if there is saline on the floor, console, or the patient’s bed.
3. If there is any saline on the floor, console, or the patient’s bed, check that the Luers on the catheter and Start-Up Kit are not cracked or damaged and that the connections are tight enough to prevent leaks.
4. If you find a leak in the Start-Up Kit, replace the Start-Up Kit and see if there is also a leak in the catheter.
5. If you do not find a leak in the Start-Up Kit, there is likely a leak in the catheter. Investigate further.

Check for a catheter leak

1. Disconnect the Start-Up Kit from the catheter. Properly cap both the catheter and Start-Up Kit using an aseptic technique.
2. Fill a sterile 10 mL slip tip syringe with sterile saline.
3. Connect the syringe to the IN Luer of the catheter and disconnect the OUT cap. Infuse 10 mL of saline – the saline should flow out the OUT Luer. If the saline does not flow out of the OUT Luer, a catheter leak is indicated.
4. Cap the OUT Luer and pull 5 cc of vacuum. Sustain for at least 10 seconds. Up to 4 mL of saline (not blood) should enter the syringe and you should be able to maintain the vacuum. If traces of blood are seen in the syringe or vacuum cannot be maintained, it indicates a catheter leak.
5. If you find a leak in the catheter, replace the catheter.
6. Replace the saline bag and re-prime the Start-Up Kit.
7. Ensure leak-tight Luer connections to the Start-Up Kit and continue the therapy.

WARNING. Never clinically circumvent the air trap alarm. ZOLL may use an air trap simulator fixture for testing, training and demonstration purposes. These are fluid filled air trap assemblies that are separate from a standard Start-Up Kit assembly. Never use this device, or other method, to circumvent the air trap alarm when the console is connected to the patient. Doing so exposes the patient to the hazards associated with air embolism should the catheter fail. Death or serious injury may result. Interference If the console does cause interference with other devices, which can be determined by turning the console off and on, try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving device.
• Increase the separation between the console and device.
• Connect the console into an outlet on a circuit different from that to which the other device(s) is connected.

Product Label
An identifying label is attached to the outside of the console near the power cord inlet. The label provides safety information and identifies the manufacturer, model, serial number, power requirements, fuse capacity, and manufacturing date for the console.

Introduction

Use of the System
WARNING. Patients must be continuously monitored. Patients being treated with the system must be checked frequently (hourly) when the system is operating. It is possible for malfunctions or misuse of the system to result in patient injury or death. The ZOLL Intravascular Temperature Management (IVTM™) System is comprised of an external heat exchange console (Thermogard XP® console) and an IVTM™ endovascular heat-exchange catheter connected via a sterile heat exchanger and tubing circuit (Start-Up Kit). These components together comprise a patient temperature-regulation apparatus employing feedback control. The catheter and the Start-Up Kit are single-use disposable devices. This manual provides operating instructions for the console and the Start-Up Kit. Catheter components are referenced where it is necessary to ensure proper use with the system components. Always refer to the catheter’s Instructions for Use for additional specific information.
Operating Life
The operating life of the catheters may vary according to design as indicated by the model designation. Always refer to the catheter’s Instructions for Use for information about the catheter’s operating life. The disposable components of the Start-Up Kit are designed for continuous use for a period not to exceed seven (7) days on a single patient. After seven days of use, remove and replace the Start-Up Kit with a new Start-Up Kit. Caution. Start-Up Kit lifetime is seven days. The designed operating lifetime for Start-Up Kit components is seven (7) days of continuous operation on a single patient. If a patient must be treated for a longer period, a new Start-Up Kit must be installed in the console. Failure to adhere to this time limit may cause injury to the patient. Product designed for single use only. Do not resterilize or reuse. Do not alter the Start-Up Kit in any way. Potential risks with re-use of a single use device include but are not limited to:

• Potentially life threatening infection
• Toxic shock due to degradation of materials
• Increased risk of thrombosis
• Reduced heat exchange power
• Device failures

Functional Description

The console can be described in terms of three major components: a recirculating chiller, a roller pump, and a temperature control system. The system is connected to the temperature-controlled catheter by two smallbore plastic tubes. One tube supplies temperature-controlled sterile saline solution to the catheter, and the other tube returns the saline solution to the console. The sterile saline is pumped through a continuous recirculating loop by a roller pump inside the console. The saline solution acts as an intermediate heat-transfer medium between the patient and the console. Sterile saline is used because it is biologically compatible with the patient and in the unlikely event of a leak in the catheter, the possibility of harming the patient is reduced to a practical minimum.
Patient temperature feedback is used to control the console. The patient’s temperature is measured by an indwelling YSI-400 thermistor temperature sensor. In response to the patient’s measured temperature, the console employs both cooling and heating. Cooling occurs when the patient’s temperature is above the set point target temperature. Heating occurs when the patient’s temperature is below the set point target temperature. The amount of heating or cooling power is proportional to the difference in temperature between the set point target temperature and the patient’s measured temperature. A basic diagram of the System is illustrated in Figure 2.1.

Figure 2.2. Controls and Display Screen
Power Indicators
An indicator lamp on the control panel is illuminated when power is switched on. A second power-on indicator is mounted directly above the power switch on the rear of the console.
Alarm Indicators
The console typically notifies users of alarm conditions in two ways. When an alarm occurs, the screen displays an alarm message, and an alarm annunciator produces an audible alarm tone (beep). You can temporarily mute the alarm tone, but cannot turn it off. If the nature of the failure prevents the console from displaying an alarm message, the alarm indicator on the control panel will be illuminated.
Control Buttons
The display head features four pushbuttons that are used to control console functions. To provide confirmation, each time a button is pressed, a “key click” sound is produced by the annunciator.

stored by the console.

Figure 2.3. Serial Interface Connector
Recirculating Chiller
The chiller consists of an air-cooled refrigeration system, reservoir heater, circulation pump, stainless steel reservoir, reservoir cover, and a temperature controller. Temperature Controller The temperature controller uses input from the patient’s temperature probe and the operator-selected patient temperature setpoint to regulate the coolant temperature of the recirculating chiller. The temperature controller constantly adjusts the coolant temperature by means of a closed-loop control system. The operator enters a setpoint that represents the patient’s target temperature. The controller cools or heats the coolant, in a range between 0º and 42º C (32º and 107.6º F) to optimally achieve and maintain the target temperature. The controller constantly displays the measured patient temperature and the target temperature. An optional mode can command the controller to approach the target temperature at a user-selected rate.

Temperature Probe Connectors
The front of the console features two connectors, labeled “T1” and “T2” which are used for connection to patient temperature probes. The primary patient temperature probe is plugged into connector T1. The secondary probe is pluggedinto connector T2.

Roller pump
Sterile saline solution is circulated through the heat exchange coil and the catheter by a high-performance, compact roller pump. It pumps by peristaltic action on the tubing installed in the pump head. The pump rotation speed is accurately controlled by an electronic speed control system.
WARNING. Finger injuries. Be careful when inserting the roller pump tubing that you do not catch your fingers with the roller. When the console is operating, do not attempt to circumvent the safety interlocks on the roller pump lid. Do not place fingers or foreign objects into the pump raceway when the pump is turning. The roller pump has sufficient torque to severely damage a finger. If a tubing leak or failure occurs in the pump raceway, the saline solution will cause corrosion in the moving parts of the rotor. Contact your ZOLL service representative.

Prime Switch
The prime switch is located on the right side of the pump. The switch is used to operate the pump to prime the tubing with sterile saline solution from the saline source. When the switch is held down, the pump runs; when the switch is released, the pump stops.

Start-Up Kit
The Start-Up Kit contains the sterile disposable components for this system. Each kit contains a heat exchange coil, air trap, saline delivery lines, saline container connector, catheter connectors, and the roller pump tubing. These components are described in detail in later chapters of this document. The components in the Start-Up Kit are designed to operate continuously for seven days, after which it must be replaced.

Data Memory
The console is capable of continuously recording patient temperature and system activity for up to 21 days.
This stored data can be downloaded to an attached computer over a serial interface using optional software furnished by ZOLL.

 Operation

Overview
This chapter explains how to start treatment and change target temperature and rate settings during treatment. It provides instructions on the proper way to end treatment, including how to download patient temperature trend data to a laptop computer and how to remove used components and dispose of them safely. Subsections at the end of this chapter provide detailed procedures for recovering from improper shutdowns, including special procedures for downloading patient temperature trend data. This Overview section presents the main features of console. After the Overview, you will find sections that describe in detail the operation of the console. The sequence of events that you must pass through in starting the console varies with the way it was last turned off. Within this section we will review the different patterns of interaction you will experience.
Specifically we will review:

• Your first case with the console
• Variations in the Setup sequence of the console
• Ending procedures

Operating States
The console has three operating states: Setup, Standby and Run. Setup When the console is first powered up, it goes through a sequence of self tests It tests its own electronics and internal sensors. These tests are called the POST (Power On Self Test). It is normal to hear two beeps during POST. Then the console tests its thermometer functions and its cooling engine. The extent of the testing during Setup and the interactions required of you by the console both vary depending upon the state of the console when it was last turned off. You can pre-set the bath temperature so that the console is either cooling or warming the bath in Setup. Patient temperature alarms are not active in Setup.
Console Self Tests
The console performs self tests both at initial power-on and then hourly during operation. These tests allow the console to check its own performance. Thermometer Functions Self Test The primary patient temperature monitoring circuit (T1) is checked during Setup and then hourly against the console’s internal high resolution calibration resistor. This is a quick test. Cooling Engine Self Test During Setup and then every four hours, during Run, the console automatically tests its cooling engine. This test takes a few minutes.
Note. Cooling Engine Self Test – The pump stops. The cooling engine self test is brief. The console stops the pump during these tests to remove the heat load from the patient during the test.The pump stops during this test. This is normal.
During these tests, the roller pump is stopped (to remove the patient’s heat load from the equation). The tests that are conducted depend upon the state of the console at the time of the test. The test(s) done is (are) as follows:

√

10 °C – 38 °C| √|

√

38 °C| x|

√  = will be performed x = will not be performed
You will not see any screen messages unless there is an abnormal result in which case the appropriate alarm state will be called.
Sensor Checks![ZOLL 601285 001 IVTM Intravascular Temperature Management

• fig 13](https://manuals.plus/wp-content/uploads/2023/01/ZOLL-601285-001 -IVTM-Intravascular-Temperature-Management-fig-13.png)

For the console to enter the next state, Standby, the following sensors must be checked and found normal.

Air Trap| There is no Start-Up Kit installed or there is a large amount of air in the Start-Up Kit chamber.
---|---
Roller Pump Lid| The clear plastic roller pump lid is not closed properly.
Check Prime Switch| The Prime Switch is being depressed (as when you use it to prime the con- sole) or has been jammed in the On position.
Coolant| The coolant level is low. Top up the coolant well with coolant.

Table 4.1. Setup Sensor Checks
If any of these sensor states are not correct you will see the “System Setup” and the problem sensor state will be highlighted in red (see Figure 4.1 above). Once you rectify the identified problems, the console will progress to Standby.
Note. Presence of patient temperature probes. The console can enter Standby without a T1 probe being connected; however, the console will not enter Run without the primary patient temperature probe (T1) connected to the console.

Standby

In Standby you can interact with the full user interface of the console. You can select the target temperature, the rate and the treatment mode.
Patient temperature alarms are active in Standby if the primary patient temperature probe (T1) is connected.
The coolant bath temperature graph is active in Standby.
From Standby you may toggle into and out of Run. You may only return to Setup by powering down the console.
Run – Treatment Modes
Once you are ready to begin treatment, you may move from Standby to Run. The console will become fully operational provided that all its sensors indicate that it is ready. Alerts will trigger if it is not. There are three treatment modes in Run: “Max Power”, “Controlled Rate” and “Fever”.
Max Power (MAX)
In this treatment option, the console aims to make the patient’s temperature the same as the selected target temperature. The roller pump may stop temporarily when:

• The patient temperature is the same as the target temperature, or
• When you change the target temperature from cooling the patient to warming the patient, or vice versa.
  The roller pump automatically resumes operating to make the patient’s temperature the same as target temperature.

Controlled Rate
In this treatment option, the console will attempt to move the patient’s temperature to the target temperature at the programmed rate of heat exchange (°C /hr). When the patient reaches the target temperature, the console will revert to the MAX treatment option i.e. it will  attempt tomake  the patient’s temperature the same asthe
selected target temperature.
Note. Controlled Rate operates in both warming and cooling modes.
Fever (FVR)
In this treatment option, the console will start cooling the patient once the patient temperature is above the target temperature. It does this by keeping the bath at its coldest permissible temperature and then operating the roller pump whenever the patient’s temperature moves above the target temperature.
WARNING. “Lo” patient temperature alarm limit with “Fever”. The console will not warm the patient when the “Fever” treatment option has been selected. The “Lo” patient temperature alarm limit ensures that an alarm occurs should the patient stop regulating his/her own body temperature. Such patients will cool to room temperature. This can occur when the patient dies or becomes comatose. Investigate all patient temperature alarms.
User Interface
The primary controls are mounted in the display head of the console. The next sections describe:

• Controls and display screen
• Menu system

If the console has been left in Standby for more than the specified time, an alarm will sound to remind that the console remains in Standby. Pressing the knob will reset the timer. The Standby Timer function will continue until either:

• The console is placed into Run.
• The Standby Timer Menu is used to deactivate the Standby Timer.
  The Standby Timer alert may be silenced for two (2) minutes by pressing the mute button.

T1/T2 Behavior
WARNING. Dislodged Foley Catheter Temperature Probe. The console can detect when a patient temperature probe is dislodged suddenly from the patient. However, it is possible for the Foley catheter patient temperature probe (T1) to become dislodged from the bladder to rest on the perineum or within the fold of the thighs. In this position, the console may not detect the dislodgement from the patient and will underestimate the patient’s core temperature. As a result, the console may inappropriately warm the patient. Failure to use a second temperature probe may  result inpatient injury.
First Use Warning – No T2 Probe
For each time the console is powered on:

1. The console will check to see if the Primary (T1) and Secondary (T2) Temperature Probes are present. The console will enter Standby without probes being present. The console will not enter Run unless the T1 probe is present.
2. When the console is first put into Run, it will check to see which probes are present.
3. If there is no T2 present, the console will ask you to verify that this is intentional. See image below.

T2 Probe Disconnection/Reconnection
If you connect a T2 probe at any time during console operation (in Standby or Run), the console will assume that use of the T2 probe is desired. If the T2 probe is disconnected, the console triggers an alarm – see below. If the you disconnect a T2 Probe in Standby, the console will not assume that this is intentional. When the console is placed into Run without a T2 Probe present, the you will see the Warning as described above again.
Accidental Disconnection T1/T2 Probe
Disconnection of the T1 probe during Run results in an alarm. The console moves to Standby. Press the knob to silence the alarm. Treatment cannot continue until the T1 probe has been replaced. Note that the patient temperature is displayed as “—“and the yellow warning banner covers the bath temperature display.

Absence or disconnection of the T1 probe during Standby results in a warning display without a persistent audible alarm. The console cannot enter Run until a T1 probe has been connected. Note that the patient temperature is displayed as “—“and the yellow warning banner does not cover the bath temperature display.

Disconnection of the T2 probe during Run results in an alarm. The console moves to Standby. Press the knob to silence the alarm. If you attempt to return to Run without reconnecting the T2 probe, you will be asked to verify your intention.
Note that the patient temperature will be displayed correctly if the T1 probe remains connected. The yellow warning banner covers the bath temperature display.

Alarms & Alerts
A detailed description of the alarms of the console is provided in later sections of this manual. See:

• Alarms and Corrective Actions on page 87
• Troubleshooting on page 91

Alerts
Alerts can be cleared by correcting the problem that caused them to occur. For example, a low coolant alert can be cleared by adding coolant to the coolant well of the console. In most cases, the console will identify and notify you to rectify alert states at power up.
In Standby, alerts are displayed across the lower half of the display screen, with the bath temperature display not obscured, against a yellow background (See Figure 4.19 – Right). Alerts in Standby are generally not accompanied by an audible alarm tone.

Figure 4.19. Disconnect alarm from Run (left) and alert from Standby (right) In Run, alarms are displayed across the full lower half of the display screen against a yellow background with the bath temperature display is partially obscured (See Figure 4.19 – Left). If an alarm occurs in Run, the console will generally revert to Standby and an audible alarm tone will sound. The exception to this is that if you depress the prime switch during Run – no audible alarm will sound and the bath temperature display will not be obscured. In both Standby and Run, a message on the screen will indicate the action required to clear the alarm or alert. During an alert, the patient temperature display is still visible and the patient temperature alarms are still active if the T1 Temperature probe is functional. Note. In the event of an alert: Investigate and rectify the cause – refer to: Alarms and Corrective Actions on page 87 and Troubleshooting on page 91. If the alert persists, call ZOLL for service.
Alarms
An alarm is more serious in nature than an alert and relates to issues that will typically require a service call. In most cases a text message, specific to the alarm, identifies the code for the alarm. For example, the screen might announce “TCM ID 01” or “MID 23” in addition to the text in Figure 4.20.

Figure 4.20. Alarm Screen In some cases, however, the alarm may be cleared by power cycling the console. For example, such an alarm would occur if the pump tubing were to become jammed in the roller pump causing the pump to slow down. If the reason for the alarm is not cleared by power cycling, the alarm will repeat each time the console is turned back on. During an alarm, the patient temperature display and the patient temperature alarms are not active. Note. In the event of an alarm: Investigate and troubleshoot the cause – refer to: Alarms and Corrective Actions on page 87 and Troubleshooting on page 91. If the alarm persists, call ZOLL for service.
Your First Case
What you need
You will need the following for each case:

• A new Start-Up Kit
• A new 500ml bag of normal saline.
• A YSI-400 compatible temperature probe e.g. a Foley catheter, rectal or esophageal temperature probe
• The blue patient connection cable to connect the temperature probe to the console
• A ZOLL heat exchange catheter
• An aseptic work area to support catheter insertion.

WARNING. Refer to catheter IFU. ZOLL heat exchange catheters are inserted via a Seldinger technique similar to a central venous line. There are specific instructions for use included with each catheter. Refer to these to understand the specific unique insertion requirements of a ZOLL heat exchange catheter.

Preparing the Console for Treatment
To prepare the console for treatment, follow these steps in the indicated order.

1. Roll the console to a convenient position near the patient’s bedside. Plug the power cord into a hospitalgrade receptacle.

2. Lock the right front caster by stepping down on the tab above the wheel.

3. At the rear of the console, near the upper left corner is the power on/off switch. Turn the switch ON. Figure 4.21. Power Switch and Power Indicator Lamp

4. The green power indicator lamp will be illuminated and the alarm will beep one long beep followed by a shorter softer beep.

5. The console performs a self-test. During this interval, the self-test screen appears on the display screen. If the self-test detects a problem, an error message will be displayed. If this occurs, refer to Alarms and Corrective Actions on page 87 for assistance. At the end of the self-test there will be two short beeps.
   Note. The software version shown in Figure 4.22 is shown for reference only; the current product may use a different software version.Figure 4.22. Self-Test Screen

Table 4.5. Setup Sensor Checks
Installing the Start-Up Kit
Hang the Saline Bag
To install the Start-Up Kit, follow these steps in the indicated order.

1. Obtain an IV bag or bottle of sterile normal saline solution. The bag or bottle must contain no more than 0.5 liter (500 ml) of solution. Hang the saline container on the hook mounted on the rear of the display head. The container hangs inside the circumference of the handle. The Top Cover

2. Open the top cover of the console. Open the transparent top cover of the roller pump.

3. A tubing circuit diagram is printed on the inside of the console top cover. Refer to this diagram when installing the Start-Up Kit. See Figure 2.8 on page 20.
   Coolant well

4. Remove the cap from the coolant well and set it aside in a clean location.

5. Check the level of the coolant. The liquid level should be between the two indicator lines on the wall of the coolant well. If the level is below the bottom indicator line, fill the coolant well with coolant (a ZOLLapproved 50% propylene glycol / 50% deionized water mixture) until the liquid level reaches the MAX line.Add coolant in an area where spills can be managed appropriately.The Start-Up Kit

6. Open the Start-Up Kit. For convenience and sterility, all items in the kit are pre-connected.

7. Insert the heat exchange coil into the coolant well.
   Figure 4.37. Installing the Heat Exchange Coil

8. Temporarily slide the air trap into the holder. Roller Pump
   WARNING. Finger injuries. Be careful when inserting the roller pump tubing that you do not catch your fingers with the roller. When the console is operating, do not attempt to circumvent the safety interlocks on the roller pump lid. Do not place fingers or foreign objects into the pump raceway when the pump is turning. The roller pump has sufficient torque  to severelydamage a finger.

9. Locate the pump tubing. Do not stretch or pull on the tubing. The tubing lengths and flanged connector allow the tubing to fit into the pump in only one direction.

10. Lift the handle on the pump rollers.

11.  Place the flanged connector of the pump tubing into the slot on the right side of the pump head.

12. Load the pump tubing around the rollers and into the channel of the pump head. You must turn the handle counterclockwise as you feed the tubing into the channel. Press down firmly on the tubing until it settles into the bottom of the channel. Once the tubing is installed, press the handle down onto the rollers until it presses into its detent.

13. Close the top cover on the pump. It will snap shut.
    Cover the coolant well

14. Replace the cap on the coolant well. Position the cap so that the heat exchange coil and tubing fits into the notch. Press down on the cap to create a tight seal. Spike the Saline Bag

15. Using aseptic technique, connect the priming line to the sterile saline container. The priming line is equipped with a “spike” connector. Hang the saline container on the hook provided. Caution. Start-Up Kit spike. The spike on the Start-Up Kit is relatively long. Be careful not to puncture the side wall of the saline bag when connecting to the Start-Up Kit.
    Prime & Fill the Air Trap

16.  Remove the air trap from its holder and hold it upside down (with the tubing connections pointing downward).

17.  Prime the air trap and the tubing circuit by pressing and holding the Prime switch. The roller pump will slowly start and take about 20 seconds to come up to operating speed. Observe the movement of saline until it fills the air trap and the entire length of the tubing. The Prime switch will only function after the console self-tests is completed.

18. Continue to hold down the Prime switch. When the air trap is completely filled with saline, tap it to dislodge any remaining air bubbles. Observe the 500 ml saline bag. When bubbles are no longer seen in the saline bag, priming is complete. Release the Prime switch.
    Nbote. Air trap. The air trap must be completely filled for proper console operation.

19. Turn the air trap right side up and insert it in the holder.

20.  Place the tubing to the catheter in the two notches at the front of the console. Place the priming line and the saline return line in the channels leading to the rear of the console. Close the top cover of the console. Caution. Damage to top cover. Do not sit on the top cover or place heavy objects on the top cover.

21.  Lift the saline container off the hook and slip the insulating jacket around the container. Carefully close the hook-and-loop fasteners at the top and bottom of the jacket. Rehang the container on the hook.

22. When the self tests are completed and the Start-Up Kit is loaded and primed, the console will enter Standby. The console is ready to be connected to the patient.

Connecting the Patient to the Console
WARNING. Verify console function first. Ensure proper functioning of the console and initiate pre-cool or prewarm (if applicable) prior to placing the catheter in the patient.
When the console has been prepared as directed in the preceding sections, it may be moved to the patient’s bedside and connected to the patient. Follow these steps in the indicated order.

1. Position the console near the patient’s bed. It must be close enough so that the temperature probe cables and the tubing can conveniently reach the patient. Route the cables and tubing safely.

2. If the primary and secondary patient temperature probes have not been placed in the patient, this should be done now. Refer to the Instructions for Use that accompany the temperature probes for information about the probes.

3. Connect the blue patient temperature cable to the YSI-400 primary temperature probe (e.g. Foley catheter, rectal or esophageal). Connect the plug at the end of the blue patient temperature cable into the connector labeled “T1” on the front of the console.

4. If you are using a secondary patient temperature probe, connect the blue patient temperature cable to the YSI-400 secondary temperature probe. Connect the plug at the end of the blue patient temperature cable into the connector labeled “T2” on the front of the console. If you are not using a secondary temperature probe, the patient MUST be monitored by a separate hospital patient temperature monitor.

5. Place the ZOLL catheter in the patient now. Refer to the Instructions for Use for information about the catheter.

6. The tubing to the catheter is supplied with the supply and return connectors connected to each other.
   Using aseptic technique, disconnect the two connectors.

7. Connect the female tubing connector to the male connector on the catheter. The gender of the tubing connectors and the catheter connectors ensures that they cannot be connected backwards.

8. Connect the male tubing connector to the female connector on the catheter. Note that the return line is equipped with an inline flow-indicator.

9. Safely route the tubing so that it is not kinked or obstructed and cannot be easily dislodged by a patient’s movement.
   The console is now ready to begin treatment.
   Once treatment has begun, confirm that saline is flowing through the tubing and catheter circuit by observing the rotation of the inline flow indicator (see Figure 4.51). If the flow indicator does not rotate freely during patient treatment, inspect the entire tubing circuit for kinks or other restrictions to flow. Tapping on the flow indicator will liberate any trapped air bubbles and return them to the saline bag.

Figure 4.51. Inline Flow Indicator
WARNING. Investigate air trap alarms. If an “Air Trap Fault” alarm occurs, it is likely that there is a leak in the tubing circuit or the catheter has failed. Refer to Alarms and Corrective Actions on page 87 for assistance. Do not keep replenishing saline that is being rapidly depleted–a problem exists that must be immediately remedied.
For additional warnings and potential risks, see Operating Life on page 13.
Setup – Variations
Setup Sequence
The Setup sequence varies depending upon the following factors:

1. The time from the last power down.
2. Whether or not you used the “End Procedure” menu option when you terminated the previous case.

Time From Last Power Down
If the console detects that it is less than 3 minutes since the last time it was powered down it will dispense with some of its self tests depending upon the state of the cooling engine at the time of power down. The idea being that, with such a short time, it is more likely than not that the power down was either unintentional (you tripped over the power cord) or an intentioned brief adjustment that required the console to be powered off (you moved the console to a new position).
The console will give you the option to use the last programmed settings. If you elect to do this you may still use the menu to change console settings in Standby.

Figure 4.52. Operate at Current Settings
If it has been less than 3 minutes since the last power down, when you power on the console, the screen above is displayed.

1. If you select “Yes” and press the knob, you will proceed directly to Standby once the console self tests have completed.
2. If you select “No” and press the knob, you will continue to be presented with screens that allow you to select operating parameters for the console prior to entering Standby starting at Figure 4.55– see below. If the console detects that it is more than 3 minutes since the last time it was powered down, it will conduct
   all its self tests. You will not be offered the  option of operating the console at the current settings.

Downloading Data After Improper Shutdown
To help prevent the accidental loss of patient trend data, the console is designed to store patient trend data if power to the console is interrupted or lost. If the console has not been properly shut-down, all patient trend data will be preserved. The next time the console is switched on, the self-test program detects the saved patient data and offers you the option to download the data to a laptop computer. If you do not wish to download the saved data, the console will delete the data before permitting set up for a new patient. To download patient trend data after an improper shutdown, follow these steps in the indicated order.

1. Plug in and switch on the console. The self-test screen appears on the display screen.
   Note. The Software Version shown in Figure 4.53 is for reference only; the current product may use a different Software Version. Figure 4.53. Self-Test Screen

Disposal of Used Components

WARNING. Single-use device – do not reuse. ZOLL intravascular heat exchange catheters and Start-Up Kit components are single-use devices and may not be reprocessed or reused. The cyclical stresses of the roller pump on the catheter and Start-Up Kit cause fatigue failures. Do not use catheters or Start-Up Kits beyond the labeled usage time. The product will fail.
Caution. Avoid contact with used components. Handle used components as medical waste.
To remove used components from the console and dispose of them properly, follow these steps in the indicated order.

1. Ensure that the patient has been disconnected from the console and that the power switch has been turned off.

2. Cross connect the loose ends of the Start-Up Kit when you disconnect it from the catheter. This will reduce the amount of fluid that has to be cleaned up later.

3. Position a large empty medical waste container or collection bag near the console.
   Caution. Do not disassemble Start-Up Kit. Do not disconnect the tubing connecting the components.
   They are removed and disposed of as a complete unit. To avoid injury, do not disconnect the saline solution container.

4. Open the top cover of the console. Open the transparent top cover of the roller pump.

5. Remove the cap from the coolant well and set it aside in a clean location.

6. Remove the insulating jacket from the saline container and set it aside.

7.  Lift the handle on the pump rollers.

8. Grasp the pump tubing and gently pull it up and out of the channel while rotating the pump head.

9. Pull the tubing out of the pump head. Press the handle down onto the rollers until it press into the detent and close the top cover of the roller pump.

10. Loosely coil the disconnected ends of the catheter tubing.

11.  Lift the heat exchange coil out of the coolant well. Hold the coil above the coolant well to allow coolant to drip back into the well.

12. Pull the air trap up and out of the holder.

13. Unhook the saline solution container from the hook.

14. Bundle up the collection of components, still connected together, and gently deposit them in the medical waste container. Take care to avoid contact with the IV container “spike.”

15. Use a disposable tissue to wipe up any spilled coolant from the top of the coolant well. Place the tissue in the medical waste container.

16. Replace the insulated cap on the coolant well. Replace the insulating jacket on the hook.
    Removal and disposal of the used components is complete. The console may now be stored or moved to its next treatment location.
    Note. Disposal of console. When the console itself has reached the end of its useful life, it must be disposed of in accordance with local governing ordinances and recycling plans for refrigerated appliances.

Temperature Trend Data

Overview
During operation, the console continuously collects and stores temperature trend data, storing a record each minute. This data is stored in memory and can be downloaded to an attached laptop computer for later analysis or plotting. Data can be collected for 21 days before the memory is filled. Periodic data download and deletion is recommended to preserve all of the stored data. If data is not downloaded before the memory is full, an error message (M Id:16) appears and the console stops treatment. The data should immediately be deleted in order to continue.
Note. M Id:16 Error Message. If during treatment the M Id:16 error message appears, this indicates the treatment file memory is full. The console stops treatment. To continue treatment, power the console off and on. Follow the prompts and select current settings. When the data download information appears, immediately either delete the data or use TempTrend to download the data and delete it. You may then resume treatment. At any time during operation, the complete record of temperature trend data can be displayed as a graph on the screen. This chapter explains how to display temperature trend data and provides details about the format and structure of the downloaded data.
Displaying the Temperature Trend Graph
To display the temperature trend graph, follow these steps:

1. Press the Press for Menu/Enter knob once. The screen displays the menu. The selection “View Graphs” will be highlighted.
2. Press the knob once. The screen will display the temperature trend graph.

Temperature Trend Graph

Temperature trend data can be displayed as an interactive graph on the screen. The display is a time-series of patient temperature (from the primary temperature probe) and console activity, plotted in two graphs. The patient temperature graph plots temperature vertically and time horizontally. The console activity graph plots cooling/warming activity vertically and uses the same time scale horizontally. An example of the patient temperature trend display is shown below.

Patient Temperature
The patient temperature graph (labeled “Patient Temp”) is scaled for any temperature between 31ºC and 41ºC (87.8ºF– 105.8ºF). The time scale can be set to any of four intervals (refer to Setting the Time Scale on page 74 for details). Figure 4.66 shows the vertical temperature displayed in degrees Celsius, and the horizontal time scale displayed for a 4-hour interval.
System Activity
The System activity graph (labeled “System”) is scaled for any console activity, from maximum cooling to maximum warming. The horizontal time scale is the same as that set for the Patient Temperature graph. The vertical scale uses a colored activity indicator:

• The red zone indicates coolant temperatures between 36ºC and 42ºC.
• The neutral point (between red and blue) indicates coolant temperature of 36ºC and also indicates when the pump is not operating.
• The blue zone indicates coolant temperatures between 0ºC and 36ºC.

Cursor
The cursor is a fixed vertical line that runs through the center of both graphs. When the temperature trend graph is displayed, you may turn the Press for Menu/Enter knob to scroll the display screen to the left or right. As data scrolls under the cursor, the top of the display screen shows the time and date of the data under the cursor.
Turn the knob clockwise to scroll to the right. As you scroll to the right, the time and date display will indicate later data. By scrolling right to the end, you can display the most current data.
Turn the knob counterclockwise to scroll to the left. As you scroll to the left, the time and date display will indicate earlier data.
By scrolling left to  the end, you can display the data collected when treatmentbegan. Status Bar Across the bottom of the display screen is a status bar which displays the patient’s temperature, the status of the console, and the target temperature for the data point under the cursor. The patient’s temperature and target temperature are displayed using the current temperature notation setting (Celsius or Fahrenheit).
The status field uses colors to display one of nine status messages that are described in the following table.

Table 4.6. Status Bar Messages

Setting the Time Scale

The time scale displayed by the temperature trend graph can be set to any of four intervals: 4 hours, 12 hours, 24 hours, or 72 hours. To set the time scale, follow these steps:

1. Display the temperature trend graph.
2. Press the Press for Menu/Enter knob once. The screen displays a pop-up menu with the choice “Set Time Scale” highlighted.
3. Press the knob once. The screen displays the message “Select interval” followed by four interval choices. The most recent choice will be highlighted.
4.  Turn the knob to highlight your desired selection. When it is highlighted, press the knob once.
5. The screen displays the pop-up menu again. Turn the knob to highlight the “Cancel/Exit” selection.
6. Press the knob once. The menu will disappear and the temperature trend graph will be displayed using the interval you selected.

Hospital Monitor Interface Accessory (HMIA)
Overview
This explains the installation, operation, and maintenance of the Hospital Monitor Interface Accessory (HMIA).
The sole function of the HMIA module is to simulate the patient temperature probe connected to the T1 port on the front of the console. Connection of the HMIA to a hospital monitor using one of the ZOLL custom cables will permit the display of an identical patient temperature on both the console and the hospital monitor, while using only a single patient temperature probe.
WARNING. The HMIA is not a replacement for the T2 Temperature probe on the console. It simply simulates the T1 Temperature probe. Use of the HMIA does not obviate the need for a second patient temperature monitoring method. Failure to use a second  patient temperature monitoring method can result in injury to the patient in
the event of a T1 Temperature Probe failure.
Operating the HMIA Connecting to the Hospital Monitor The HMIA simulates a standard YSI-400 temperature sensor, such as in a patient temperature sensing Foley
catheter or rectal probe.
The HMIA is connected to a hospital monitor via a ZOLL custom interface cable included with the HMIA. These cables have connectors that are identical to the connectors of Foley and rectal patient temperature probes.
One end of the ZOLL interface cable plugs directly into the standard patient cable of the hospital monitor. In this way, the hospital monitor connects to the HMIA interface cable in the same fashion as it would connect to a Foley or rectal temperature probe. (See Figure 4.72).

The other end of the ZOLL interface cable plugs into the HMIA connector labeled T1 out. (See Figure 4.73).

To begin operation
The operation of the HMIA is very simple. There is no independent on/off switch. As soon as the console is switched on, the HMIA automatically begins functioning.
Connect the custom ZOLL interface cable to the patient cable of the hospital monitor. (See Figure 4.72). Plug the other end of the ZOLL interface cable into the HMIA connector labeled “T1 out”.
The set-up is now complete.
Controls and indicators on the HMIA
The HMIA has the following control/indicators: a reset switch, a green power indicator and a red warning light. The front panel of the HMIA is illustrated in Figure 4.74.

The meaning of the symbols on the front panel is as described in the table below

clip, or similar sized device, into the hole until you feel a “click” and then withdraw the paper clip.
| Caution LED| This red light indicates that there is a malfunc- tion in the HMIA.
| Power LED| This green light indicates that the HMIA is receiving power from the console.
RS232| RS-232 Serial port connector cable| This short extension cable is connected to the RS-232 data port connector on the back of the display head.
T1 out| Patient temperature output connector| This connector accepts the custom ZOLL inter- face cable.
SYSTEM| Console umbilical cord connec- tions| One connector is attached to the round, multi- pin connector on the back of the display head via a short cable. The other connector mates with the umbilical cord of the console.

Table 4.7. HMIA Control/Indicators
Operating States
The HMIA has the following operating states: Start-up and Run.
Start-up
When the console is powered on, illumination of the Green LED is indication that power has been supplied to the HMIA. If there is no power to the HMIA the Green LED is not lit and the hospital monitor, if attached to the HMIA, should detect this as a probe disconnection or temperature probe error.
Once powered, the HMIA immediately establishes its link with the console and performs a series of self tests including self-calibration – see below.
Run
The HMIA is designed to provide a variable resistance value that is interpreted by YSI-400 compliant hospital monitors as patient temperature. The patient temperature is obtained via the T1 connection of the console.
Calibration
HMIA performs a self-calibration at Start-up. It will also perform a self- calibration upon reconnection of the RS232 port  (for example, you might temporarily disconnect
the HMIA to  allow accessfor  datadownload).  Selfcalibration takes less than half a second. During self-calibration, it may be detected by the hospital monitor as a disconnected probe. At the end of self-calibration the HMIA  will automatically return to Run.
Installation
The HMIA is quickly and easily installed. Prior to installation of the HMIA, verify that the console has the correct software to support the HMIA. The software version is displayed during initial start-up of the console per Figure 4.75. The first number in the Software Version must be equal to or greater than 1.04 (See Figure 4.75).

Figure 4.75. Console Software Version
If your console does not have the compatible software version, then the correct software will need to be installed for the HMIA to function. Failure to install the correct software prevents the HMIA from functioning but it has no adverse affects on the console.
Installation Equipment
The following items are necessary to install a HMIA.

1. Console with correct software.

2. Hospital Monitor Interface Accessory (HMIA)

3. TP-400 test fixture with adapter cable that mates to the T1 connector of the console

4. Air trap assembly filled with water.

Data Download
You may download data from the console at any time. Simply disconnect the HMIA RS-232 connector from the RS-232 port on the back of the display head. Then download data per the instructions in the TempTrend CSV IFU.
This procedure will not delete the data from the console. The data is simply copied from the console to the laptop.
Reconnect the HMIA RS-232 connector when you have finished.
You cannot damage the HMIA by mistakenly “downloading data” into it.
The HMIA does not store data.
Note. When you disconnect the HMIA RS-232 connector from the display head, the HMIA will stop sending data to your hospital monitor. The hospital monitor will detect this as a patient disconnection or a very low patient temperature. Depending upon the set-up of your hospital monitor, this may or may not result in a patient temperature alarm on the hospital monitor.

Troubleshooting

The HMIA has a very limited user interface. The only function of the HMIA is to simulate the patient tempera- ture probe connected to the T1 input port of the console.
This troubleshooting guide deals only with the HMIA. It is incumbent on the technician doing troubleshooting to verify Items 1 through 4 below prior to troubleshooting of the HMIA:

1. The console is powered on, operational, and reporting a valid temperature on the display screen.
2. The hospital monitor is on and operational.
3. The hospital monitor conforms to the YSI-400 specifications.
4. All cables are connected.
   a. RS232 from the HMIA to the display head.
   b. The circular connector on umbilical cable of the console is plugged into the HMIA.
   c. The HMIA is attached to the circular connector on the display head.
   d. The hospital monitor is connected to one end of the ZOLL interface cable of the HMIA.
   e. The other end of the ZOLL interface cable is connected to the HMIA.

Alarms and Corrective Actions

Overview
This chapter lists alarm messages that may appear on the console display during operation. If an alarm occurs, refer to the following table for information about the cause and corrective actions you can take to remedy the problem.
Please note that in many cases the console will automatically restart when the condition that generated the alarm has been cleared. In other cases, you must take corrective action and then restart the console.
WARNING. When treating a patient with the console, appropriately qualified medical staff must routinely and closely monitor the patient. Audible and visual alarm signals generated by the console require the authorized individual to remain in close proximity to the patient throughout the procedure.
Note. Alarm priorities. In accordance with the IEC 60601-1-8:2006 safety standard, the console alarms have been categorized as High, Medium, and Low priority. High priority alarms are indicated by red flashing text on the display and require prompt attention from the operator to prevent irreversible injury or death. Medium pri- ority alarms are indicated by a yellow banner and require attention from the operator to prevent reversible injury or discomfort to the patient. Low priority alarms are displayed with a yellow banner and delay the treatment of the patient until they are addressed by the operator.
Alarms and Corrective Actions
Alarm messages are grouped according to their priority.

Events Requiring Technical Assistance
Caution. The console has multiple internal alarm states – see Alarms and Corrective Actions on page 87. As described in this manual, some are remedied by the user action e.g. Filling the coolant well with coolant will rectify the coolant level alarm. There are others that may be alleviated, in some cases, by power cycling the console (i.e. turning it off and then back on). If neither user action nor power cycling the console clears the alarm – Do not use the console. Call a ZOLL Service Representative for service of any alarm that does not clear. Immediately discontinue using the console and seek advice from your ZOLL service representative if any of the following events occur: • The console repeatedly trips an outlet equipped with a ground fault circuit interrupter (GFCI).

• The protective fuse repeatedly blows.
• Fluid is observed leaking from the console.
• The console emits an unusual odor when operating.
• The console produces loud or unusual noises when operating.
• The display screen, control knob, or control buttons fail to operate as expected.
• The console has been exposed to fire, flood, or hazardous substances.
• The console has suffered potential damage due to improper storage, rough handling, or being dropped.

Maintenance

Overview To ensure safe operation and a long service life, the console must be periodically maintained. This chapter describes the scheduled and unscheduled maintenance tasks that must be performed by the user. Scheduled maintenance tasks must be performed at least as frequently as recommended in this chapter. If your console is subject to very long periods of continuous use, you may be required to perform these tasks more frequently than the schedule recommends. The frequency of performing unscheduled maintenance tasks depends upon the manner in which you use the console. Most of these tasks are performed when an inspection indicates that they are necessary, or after a problem is discovered. Failure to perform the maintenance tasks listed in this chapter may cause degraded performance of the console or may reduce the operating life of its parts. To ensure safe operation of the console, preventive maintenance and service, including a comprehensive technical inspection and electrical safety test, is required annually. Contact your local sales representative for information on preventive maintenance pricing and complete service packages available in your region.
WARNING. No user-serviceable parts inside the console. Only ZOLL- authorized personnel may service and repair the console.

   Note. Console disinfection. To disinfect the console, ZOLL recommends PDI germicidal disposable wipes (EPA Reg. No: 9480-4). An equivalent product approved by local authorities may be ® ® Super SANI-CLOTH used. It must include at least 55% isopropyl alcohol or other approved non-corrosive hospital-grade disinfectant. ZOLL highly recommends testing the disinfectant on a small area on the outer surface of the console prior to wiping all surfaces of the console. Follow directions provided by the manufacturer of the disinfectant. The hospital determines the effectiveness of the disinfectant.

3. Wipe down the outside surfaces with a water-dampened cloth to remove remaining spots or residue.

4. Slide out and remove the condensate collection pan from under the front of the console (see Figure 7.1).

5. The pan may be washed in hot soapy water. Never use solvents or abrasive cleaners on the pan. Dry the pan when finished and reinstall it in the console.
   Note. Do not operate the console without a condensate collection pan properly installed. Failure to do so may allow water to accumulate on the floor under the console.

Drain Coolant
It may become necessary to drain and clean the coolant well because the coolant has become contaminated, or to prepare the console for shipment.
Required Tools and Materials
You will need the drain line and connector assembly (supplied with the console), and a 2-liter waste container to perform this task. Drain the coolant in an area where spills can be managed appropriately.
Procedure
To drain the coolant well, follow these steps in the indicated order.

1. Unplug the console.
2. Remove the cap on the coolant well and set it aside on a clean surface.
3. Visually inspect the coolant well for discolorations or foreign matter.
4. Remove the front panel of the console by pulling the panel straight away from the front of the machine (no tools are required to remove the panel). Near the bottom left corner of the console is a drain hose held by a clamp and the drain coupler.
5. Place the open end of the drain hose into a suitable container or position it above a floor sink or drain.
6. Push the connector on the drain hose into the drain coupler on the coolant well (refer to Figure 7.3).
7. As soon the connector is firmly seated in the coupler, coolant will automatically begin to flow through the line.
8. Wait until the coolant flow has stopped. Disconnect the drain line by pressing down on the metal tab on the coupler. Gently pull out the drain hose.
9. Dispose of the used coolant.
10. Wipe the coolant well dry. Visually inspect the drained coolant well for discolorations or foreign matter.
11. Thoroughly wipe the coolant well with at least 55% isopropyl alcohol or other non-corrosive hospitalgrade disinfectant.
12. Rinse the coolant well with coolant. Do not rinse with saline.
13. Reconnect the drain hose as described in steps 4-7 and drain the liquid used for cleaning. Dispose of the liquid.
14. Rinse the coolant well with coolant. Refer to Table 7.1, “Scheduled Maintenance,” on page 95.
15. When cleaning is complete, you may leave the coolant well empty (to prepare it for shipment), or refill it with coolant . Refer to Table 7.1, “Scheduled Maintenance,” on page 95 and Preparing the Console for Treatment on page 46 for details.
16. Replace the cap on the coolant well.
17.  Replace the drain hose in the clamp. Replace the front panel on the console.

Spillage
Both saline and coolant are corrosive and electrically conductive. Although the console is designed and tested to be in compliance with the spillage protection requirements of IEC 60601-1, it is important to clean up spillage quickly:

1. To ensure a safe work environment. Spillage, especially of coolant, can result in a very slippery floor.
2. To minimize the risk of corrosion or damage to the console.

Spillage is most likely under the following conditions:

1. During set-up of the Start-Up Kit. Spillage of saline in this case should be cleaned up as with the handling of any infusion fluid.
2. During filling or emptying of the coolant well. The coolant may be safely wiped with paper towel and the towel disposed of in the standard trash. Propylene-glycol: Water mix is slippery on sealed floors.
3. In the event of an air trap alarm. With any air-trap alarm, investigate to see if there is spillage into the raceway. Remove the rotor and blot dry the raceway and motor shaft.
