1.1. Introduction
The CARE vent® ALS Handheld Resuscitator provides trained individuals with a safe and effective means of providing artificial ventilation during respiratory and/or cardiac arrest.
The CARE vent® ALS Handheld Resuscitator is lightweight, portable, and extremely durable. Designed for the demands of the emergency medical and rescue environment, they can be operated anywhere an oxygen cylinder or piped wall outlet is present.
Note: An Automatic and Manually Triggered Resuscitator is considered a critical device, and its components considered critical components. Only those individuals trained in Cardiopulmonary Resuscitation and the operation of oxygen-powered ventilators should use this equipment. Thoroughly review this instruction manual before use.
INTENDED USE:
The CARE vent CA resuscitator is intended for use in pulmonary resuscitation during respiratory and/or cardiac arrest, and to provide short term ventilatory support for both intra-hospital and inter-hospital of non- breathing patients.
Note: This resuscitator is intended for first response to a breathing emergency only and that patients must be transferred to a transport and emergency ventilator as equipment becomes available.
WARNING
Resuscitator used in contaminated environments can be hazardous unless entrainment is prevented or appropriate filtration is provided.

1.3. Features
The CARE vent® ALS Handheld Resuscitator is a pneumatically powered, time/volume cycled ventilatory resuscitator with the added feature of a Manually Actuated, Automatic Ventilation Override Button (Manual Button) to allow the operator to control
the ventilations manually at a rate and volume they desire.
In addition the CARE vent® ALS allows the breathing patient to “Demand Breathe” on 100% oxygen while their inspiratory efforts causes the automatic cycling to cease. Should they stop breathing, the ventilator will automatically restart cycling in the setting selected.
The “pneumatic logic circuit” can be run on either approved, compressed, breathing air or medical oxygen. The unit is self contained and only requires its attachment to a regulated oxygen or air supply (as specified) for immediate use.
The CARE vent® ALS Handheld Resuscitator:

• Delivers 100% oxygen during resuscitation (when attached to an oxygen source).
• Meets American Heart Association/J.A.M.A. recommendations for C.P.R.
• Provides physiologically normal respiratory rates and volumes.
• Has an Audible Airway Pressure Limiting System set in accordance with the recommendations of the American Heart Association/ JAMA.
• Is lightweight and extremely durable.
• Is designed for emergency resuscitation and pre-hospital care / patient transport and for resuscitation and interdepartmental transport in the hospital environment where the potential patient use is with children and adults.
• Has a Manually Actuated, Automatic Ventilation Override Button (Manual Button).
• Has a seven position selector providing six, preset, automatic settings for a range of patient sizes from children to adults with tidal volumes and frequencies of ventilation in line with established guidelines for the range of patient sizes indicated and an OFF position to allow the ventilator to be left in a “standby mode” with the oxygen supply turned on.
• Provides “Demand Breathing” with automatic cycling shut off and re-start.

  1.5. Safety Precautions
  The CARE vent® ALS Handheld Resuscitator is designed to provide emergency ventilatory support to patients suffering from respiratory and/or cardiac arrest.
  The CARE vent® ALS Handheld Resuscitator is intended for use by suitably trained and qualified personnel. The following precautions should always be observed:

  1. Do not leave the patient unattended.
  2. When not in use, always turn off the cylinder.
  3. Never allow oil or grease to come into contact with any part of the cylinder, regulator or resuscitator.
  4. Do not disassemble any part of the resuscitator except where described in this manual, as any unauthorized disassembly will invalidate the warranty.
  5. After use, always ensure that all components are cleaned in accordance with the instructions provided in this manual.
  6. Ensure that all components are reassembled correctly and that all items are replaced in the carrying case.
  7. After use, always ensure that a full air or oxygen cylinder is attached before returning the unit to its normal storage position.
  8. Ensure that a new sealing washer is used every time you attach the regulator to the cylinder.
  9. It is recommended that an alternative means of ventilating the patient be available in case of gas supply failure.

 Pre Use Function Check

2.1. Set Up
Along with the contents of the shipping cartons you will require the following items to enable you to undertake the pre-use functional check:

1. Full oxygen cylinder
2. Oxygen regulator with a 60 PSI 9/16 DISS outlet. The regulator must be able to output a minimum of 120 L/min at no less than 45 PSI ( 3.1 Bar).

Having connected the supply hose to the regulator, ensure that the Setting Selector is in the OFF position and turn on the oxygen supply. Using a mild soap solution, spray the input connection to the resuscitator to check for leaks. If any leak is present, tighten the connection and re-test.
Once no leaks are found, connect the Test Lung to the 15/22 mm patient connector on the resuscitator. Using the Sliding Setting Selector , select the first automatic setting.
2.2. Testing of the Individual Features of the Ventilator.
The following features can be individually tested during the preuse Functional Check:

1. Maximum Airway Pressure and Audible Alarm
2. Frequency/Tidal Volume Adjustment
3. Manual Ventilation
4. Demand Valve Function and Automatic Circuit Shut Off

Operating Procedure

3.1. Connecting the Supply Hose and Patient Circuit
The supply hose provided is attached to the oxygen inlet on the rear of the resuscitator and is tightened “finger tight” (fig 1).
WARNING ****
The use of excessive force in tightening the supply hose may damage the seal and /or thread.
The facemask is attached to the patient connection port by simply pushing the mask onto the 22mm taper.

Connecting the supply hose (fig 1)

3.2. Manual Ventilation and Cardiac Compressions.
The CARE vent® ALS Handheld Resuscitator has a Manually Actuated, Automatic Ventilation Override button (Manual Button) to assist in the timing of ventilations in conjunction with external cardiac compressions.
By using the Manual Button, the operation of the ventilator can be easily timed with the chest compressions so as to avoid the potential problem of the aspiration of stomach contents due to gastric distension which may occur if overlap of chest compression
and inflation occurs. (It has been shown in some studies that, in patients that are intubated, this overlap of compression and inflation may increase cardiac output without the danger of gastric distension.) The flowrate provided is equivalent to the setting on the automatic setting selector providing flowrates equivalent to the size of patient being ventilated, thereby reducing airway pressures and the risk of aspiration of stomach contents still further.

1. If no respiratory effort is observed, position yourself above the patient’s head and apply the face mask over the patients mouth and nose. The thumb and index fingers are used to hold the mask to the face while the remaining three fingers of each hand are placed along the angle of the jaw. A tilt action is used to hyperextend the neck and move the jaw forward.  This helps displace the tongue away from the back of the throat and maintains an open airway.
2. Select the tidal volume/frequency of ventilation for the size of patient being resuscitated. Depress the manual button and observe the rise of the patient’s chest. Release the button when chest rise is adequate.
3.  If the patient’s chest does not rise or gas escapes around the mask or the patient valve(A) (Fig.3) operates, reposition the patients head and adjust your hand position to obtain an effective mask seal and an open airway.
4. Monitor the patient’s skin, nailbed and lip color.
5. If mask indicates signs of vomitus, remove immediately and clear the airway. Restart ventilation immediately after clearing airway.
6. Continue ventilation at an appropriate rate until relieved or until spontaneous breathing returns.

3.3. Automatic Ventilation

1. If you have been ventilating manually simply release the manual button and after a short pause (5 – 8 seconds) (1723 seconds in the G05 model), the ventilator will commence automatic cycling at the rate and volume selected. If you are commencing automatic ventilation immediately, rotate the setting selector to the setting appropriate for the size of patient being ventilated and the ventilator will commence automatic cycling (fig 1).
2.  Closely observe the patient’s chest movements. If there is any leak from around the mask or any obstruction in the patients airway (blow off valve will operate) reposition patients head and adjust mask and hand position to ensure a good airway and mask to face seal.
3. Should repositioning the mask and adjusting hand/neck position not resolve the situation adjust the automatic selector control to establish the correct tidal volume. This is accomplished by moving the control toward the child setting if the blow off valve
   operates or towards the adult setting if chest rise is insufficient. This can be done by simply using your thumb to slide the control without removing your hand from the mask.

WARNING **
Automatic ventilation of the patient who is intubated or whose mask is held in place with the optional head harness system, does not mean that the patient is safe to be left unattended and constant observation of the patient’s pulse and chest movement must be continued.
WARNING **
The use of gas pressure regulators that do not maintain a minimum output pressure and flowrate in line with the requirements of the specification may cause the device to fail resulting in the patient not being ventilated.

Automatic Adjustable Setting Selections (fig 2)
3.4. Action to be taken if patient vomits during resuscitation
Should the patient vomit into the mask during resuscitation the following steps should be followed to clear the foreign material:

1. Remove the mask from the patient’s face and clear any foreign material from the patients airway. Depress the manual button or allow the resuscitator to cycle automatically for a few breaths to clear the mask and valve of foreign material.
2. If depressing the manual button repeatedly or automatically cycling the resuscitator does not clear the foreign material from the patient valve,either disconnect the resuscitator from the gas supply or turn the selector to the OFF position, remove the facemask and unscrew patient valve swivel housing (a) from the resuscitator body being careful to ensure that the diaphragm (b) is retained (Fig.3).
3. Shake out any foreign material from the resuscitator, diaphragm, face mask and patient valve swivel housing.
4. Rotate the selector to the appropriate position and either operate the manual button to blow out any contaminant or cycle automatically for a few breaths.
5. Re-assemble diaphragm, patient valve and face mask and operate the manual button or automatically cycle the resuscitator for a few breaths to ensure correct function.
6. Restart resuscitation as previously indicated.

Note: When using the single use patient valve, vomitus may be forced past the diaphragm and contaminate the bio- filter. This may necessitate the use of a new single use valve.
3.5. Demand Breathing and Automatic Circuit Shut Off
Should the patient commence spontaneous breathing at a flowrate of greater than 30 lpm for more than 1 second the CARE vent® ALS will sense the patient’s inspiratory effort and will stop cycling automatically allowing the patient to “Demand Breathe” at their
own rate and volume on 100% oxygen (if connected to an oxygen supply). If they cease spontaneous breathing the ventilator will recommence automatic cycling after a delay of 5 – 8 seconds (depending on the depth of the patients previous respiration) without intervention by the rescuer.
Note: The use of a Transport Ventilator Circuit with the CARE vent® ALS will increase Demand Valve Triggering Pressure due to the secondary patient valve. The use of the Transport ventilator Circuit does not increase the patient valve headspace.
