3. Locate the cuff in such a way that the artery mark ” ” is at a location where the clearest pulsation of brachial artery is observed.

10

User Manual for Vital Signs Monitor (VET)
Figure 3.7 Demonstration for cuff location Notes: For cats and dogs, the preferred position for all NIBP measurements is either left or right lateral recumbency for both sedated
and awake conditions. This will position the limbs fairly close to heart level and makes it easier to hold an awake animal. When putting on the cuff, wrap it around the limb evenly to appropriate tightness. Remember to empty any residual air in the cuff before the measurement commences. Using a cuff that is the wrong size may give false and misleading results. Pressure Accuracy Verification Pressure Accuracy Verification is a function to inspect the accuracy of pressure measurement by the NIBP module inside the device. Technician or equipment manager should do pressure accuracy verification every half year or year in order to check if the pressure measurement still conforms to the requirement of product performance. If the deviation is beyond the declared specification, it is permitted to return it to factory for repair or calibration. Before verification, please connect the monitor to a precise pressure meter such as a mercury pressure mete, which is used as the reference meter.

Manual valve Inflation balloon

Increase the pressure manually through the inflatable balloon

Figure 3.8 Connection of Pressure calibration fixture At this mode, the monitor can activate the inflation, so the pressure will increase automatically until it exceeds the limit value specified in table A. This pressure limit value depends on the veterinary patient type selection as shown in table A:

Big animal

200mmHg

Small animal

120mmHg

Table A During the inflation, the Monitor will close the deflating valve, and the pressure value will be shown during the process. If there is no manual deflation operation, the pressure will persist until deflation by manual operation, so it is necessary to use a manual valve for doing adequate deflation in several steps to verify the pressure accuracy in the full scale of measurement range. Mode 2: Manual inflation for the pressure accuracy verification. At this mode, the pressure should be increased manually by a pumping balloon, and the verification can be done by applying different pressure value manually. If the increased pressure exceeds the given limit as shown in table B, the Monitor will deflate automatically because of over- pressure protection.

Big animal

240mmHg

Small animal

140mmHg

Table B After the verification, do press the button again to return to normal working mode, then continue other operation, or the
NIBP key will be invalid.

Pressure accuracy verification must be operated by technician or equipment manager. Doctor or nurse is not allowed to do the verification, it is very dangerous especially when the pressure cuff is still on veterinary patients.
Air Leakage Check

12

User Manual for Vital Signs Monitor (VET)
In order to avoid significant error of blood pressure measurement or even no measurement result caused by air leakage in the pneumatic system including the cuff during measuring, it is recommended to check if there is leak in the pneumatic system as well.
Please remove the cuff from patient while performing the leakage check.
Safety Instructions for NIBP Monitoring
When taking the blood pressure measurement on a small animal, do NOT operate in the “Big animal” mode. The high inflation pressure may cause lesion or even body putrescence. Even though the monitor can identify the cuff type so it will stop inflation and indicate “Cuff error” when taking the blood pressure measurement for a small animal in the “Big animal” type setting. The user (doctor or nurse) should pay more attention to select the correct veterinary patient category.
It is recommended to take the blood pressure measurement manually. Automatic measurement should be used at the presence of a doctor/nurse.
NIBP monitoring is prohibited to those who have severe hemorrhagic tendency or with sickle cell disease, or partial bleeding will appear.
Do NOT bind NIBP cuff on limbs with transfusion tube or intubations or skin lesion area, otherwise, damages may be caused to the limbs.
If the veterinary patient is moving or suffering tremble, hyperkinesia or arrhythmia, it may cause the inflation time of inflatable balloon endures longer, which may not only prolong the NIBP measurement time, but also result in the body wrapped by the cuff is troubled by purpura, hypoxemia and neuralgia because of the friction.
Before the measurement is carried out, select an appropriate monitoring mode depending on the patient’s type (big animal and small animal).
It is prohibited to wrap the cuff to a limb with skin lesion. DO NOT take blood pressure measurement from a limb receiving ongoing transfusion or intubations. Because it may damage
the limb tissue around the intubation if the transfusion becomes slower or blocked during the cuff inflation. The windpipe which connects the cuff and monitor should be straightway without any tangle. When a large animal (such as dog) is monitored, the machine may fail in giving the blood pressure measure if small
animal (such as cat) mode is selected. Prior to use of the cuff, empty the cuff until there is no residual air inside it to ensure accurate measurement. Do NOT twist the cuff tube or put heavy things on it. When unplugging the cuff, hold the head of the connector and pull it out. The NIBP measurement will not be affected when the monitor is connected to the veterinary patient on whom the
electro-surgical device such as defibrillator or electro-surgical knife with high frequency is being used.
The appearance of arrhythmia results in irregular heart beat which may affect the accuracy of NIBP measurement data. It is recommended to take the NIBP measurement again at this situation.
The Blood pressure measurements determined with this device are equivalent to those obtained by a trained observer using the cuff/stethoscope auscultatory method, within the limits prescribed by the American National Standard, Manual, electronic, or automated sphygmomanometers.
3.6.2 SpO2 Sensor Connection Please select the appropriate animal type (such as big animal, small animal) and measuring site according to the tissue thickness of the selected animal and measuring site when making measurement of the animal’s SpO2. Animal type: big animal or small animal; Thinner or
13

User Manual for Vital Signs Monitor (VET)
lighter tissues (tissues without bone): animal ear and tongue; Thicker or darker tissues (tissues with bone): leg, claw and tail. SpO2 sensor is a kind of very delicate part. Please follow the given steps and procedures while using it. Failure to operate correctly can cause damage to the SpO2 sensor. 3.6.2.1 SpO2 Sensor Installation The device is equipped with the universal Y-type sensors including different adapters (i.e. clips and wrapper) for different animal type and the various measuring sites, as shown in figure 3.8B and 3.9B. Please select the appropriate sensor adapter according to its shape size and the measuring site. Generally, clip adapter will be more appropriate if the measuring site is ear or tongue; and wrapper adapter will be more appropriate if the measuring site is tail or leg. Installation of SpO2 Sensor with Clips 1. Fix the Y-type sensor cable to the slot as shown in figure 3.8A; 2. Fix the receiving part and emitting part to the clip, as shown in figure 3.8B. For thinner or lighter tissues (such as ear or tongue), if the
transmitted light is too intensive for measurement (no readings), then the user can refer to figure 3.8C to wrap layers of self-adhesive tapes to the receiving part and emitting part, a single layer or 2 layers will be OK.

User Manual for Vital Signs Monitor (VET)
Before wear the SpO2 Sensor, please clip the emitting part and receiving part of the Y-type sensor to the round hole and button hole of the cloth wrapper respectively, as shown in figure 3.9A and 3.9B.
Put the measuring site onto the cloth wrapper (between receiving part and emitting part), then wrap the cloth wrapper and paste the adhesive clip to the cloth wrapper to fasten the measuring site, refer to figure 3.11C and 3.11D. Note: emitting part and receiving part of the sensor should aim at each other. Otherwise, the signal quality and intensity will be affected. If the animal’s limb (leg or tail) is too big, then the user can cut the buttonhole longer by scissors, so that the emitting part and receiving part of the sensor can aim at each other properly.

3.6.2.2 SpO2 Sensor Connection Operating procedure: 1. Connect the port of SpO2 sensor to one end of SpO2 extension cable, and close the plastic cover, connection demonstration is as shown
in figure 3.10B.

2. Connect the SpO2 extension cable connector to the socket marked with “SpO2” on the right signal input panel of the monitor.

3. Put the installed SpO2 sensor on the appropriate measuring site. The first choice of measuring site for animal is their ears, then the

second choice is their legs or tails when the animal is calm or quiet. If there is no steady result can be measured from the mentioned sites

above, it’s recommended that make measurement on tongue when the animal is under anaesthesia. There are different setting items in

this monitor according tothe equipped SpO2 module with different technology. Please make sure that the setting conforms to the actual

measuring site. For example, if the measuring site is set as “Ear / Tongue”, then the sensor must be clipped on animal’s ear or tongue, as

shown in figure 3.11A and 3.11B; if the measuring site is set as “Leg / Tail”, then the sensor must be wrapped on animal’s leg or tail, as

shown in figure 3.11A and 3.11B. If the monitor has “Response speed” setting item, then the user can make corresponding selection

according to the measurement accuracy and tracking speed. For example, the “Fast” setting can track the quick change of SpO2 , but it will

be less accurate. While the more accuracy can be obtained but wirh slow response if “Steady” setting is selected.

The first choice of measuring site is ear, leg or tail. If the measured result is not ideal, then change the measuring site to tongue, but the animal should be under anaesthesia when make measurement.
If the monitor has configuration item for measuring site (such as ear/tongue, leg/tail), please make sure that the setting conform to be the actual measuring site before make measurement. For example, thin tissues response to ear or tongue, and thick tissues response to leg or tail.
When measuring on thinner or lighter tissues, it’s possible that the sensor’s light coming through the very thin tissues is too strong to be properly interpreted by the device, which causing no readings. In this situation, the user can wrap a single or two layers of self-adhesive cloth on the sensor to reduce the intensity of the light hitting the detector.
If the measured tissue is too thick, then the user can shave off /wet the hair on measuring site, or move to another thinner tissue. If the measured tissue is too thin, then the user can move the sensor to other tissues or wrap a single or two layers of
self-adhesive cloth on the sensor. As a general rule, measuring SpO2 for animal is performed when the animal is calm or under anaesthesia, and the first choice of
measuring site is their ears, then legs, and tail, the last choice is their tongues. To avoid make SpO2 measurement under the light including surgery lamp, halogen lamp, fluorescent lamp and infrared heating
lamp. Making effective steps to calm the animal to avoid measurement error. Check the device to make sure that there is no visible damage that may affect user’s safety or measurement performance with
regard to sensors and clips. It is recommended that the device should be inspected minimally before each use. If there is obvious damage, stop using the device. Special attention should be paid while the SpO2 sensor is used constantly under the ambient temperature over 37°C, burning hurt may occur because of over-heating of the sensor at this situation. Continuous use of finger clip adapter may result in discomfort or pain, especially for those patients with microcirculatory problem. It is recommended that the sensor should NOT be applied to the same tissue for over two hours, change the measuring site periodically if necessary. Change the measuring site every 2 hours if the ambient temperature over 35°C.
16

User Manual for Vital Signs Monitor (VET) SpO2 measuring position must be examined more carefully for some special patient. Do NOT place the SpO2 sensor on the limb
with edema or fragile tissue. Do NOT put the SpO2 sensor and pressure cuff on the same limb, otherwise the NIBP measuring will affect SpO2 measuring and
cause the alarm error. The SpO2 sensor cannot be immerged into water, liquor or cleanser completely, because the sensor has no capability to resist the
harmful ingress of water. When plugging or unplugging the SpO2 sensor, be sure to hold the head of the connector and pull it out. Check the SpO2 sensor and cable before use. Do NOT use the damaged SpO2 sensor. When the temperature of SpO2 sensor is abnormal, do not use it any more. Please do not allow the cable to be twisted or bended. Do NOT use the damaged SpO2 sensor. 3.7 Loading printer paper (if printer is installed) Operation procedures for loading printer paper:

5.3 Alarm Reset and Silence

Press

(Alarm Silence) key to pause the audible alarm temporarily or reset the current alarm condition. During the monitoring

process, press “Alarm Silence” key shortly to start the alarm silence for 2 minutes. The counting down time shows up on the upper left

corner of the screen once the alarm silence is activated. Long pressing “Alarm Silence” key will reset the current alarm condition, that

means the sound mute for this alarm will not resume unless another alarm condition occurs. During the alarm silence period, if there is a

new alarm condition other than the current one occurs, the device will generate the audible alarm indication again automatically. After

the end of alarm silence period, if the current alarm condition still exists, then the audible alarm indication will resume as well.

When the monitor generates alarms, the user can press period when necessary..

key to reset or pause the audible alarm indication for a given silence

DO NOT silence the audible alarm or decrease its volume if patient safety could be compromised.

For the alarm conditions of “Can not detect SpO2″ and”Can not detect HR/PR”, the audible alarm indication will only last for about 7 seconds.

Alarm signal can be reset, but it can NOT be deactivated all the time.

5.4 Alarm Settings
1 Except volume of audible alarm can be adjustable, the other properties of the alarm signal cannot be adjusted by the user, such as alarm priority setting, alarm light flashing and so on. In addition, all alarms in this monitor are “non-latched” type, that is to say, when the alarm condition does not exist, the corresponding alarm signal will automatically stop. The alarm volume range is shown as below: High: 45dB80dB (The distance from the front of device to the test instrument is 1m) Medium: 45dB75dB (The distance from the front of device to the test instrument is 1m) Low: 45dB70dB (The distance from the front of device to the test instrument is 1m)
2 When the icon displays on the screen and its color is red, that means the alarm volume is 0 (alarm is mute), at this time the user should pay more attention to the patient.
It is suggested that the users should not change the alarm volume lower than the factory default setting if close and constant attention could not be paid to the patient, otherwise the negligence of alarm event might cause irreversible harm to the patient.
During the alarm silence period, any new alarm event can activate the audible alarm again and the audible alarm function resumes normal state.
After the alarm silence time counts down to 0, or the operator presses the Alarm Silence Key again, then the system will resume to the audible alarm signal if this alarm condition still exists.
The alarm limit value should NOT be set to exceed the declared measuring or display range, or the system alarm signal will not be generated.
3 Alarm settings are non-volatile, that means the previous settings will still sustain if the monitor is powered off (by accidental power interrupt or by normal power down) and reboot.
4 When pressing the Alarm Silence Key, the system will stay on “Alarm Silence” status and this status will last for 2 minutes. 5 It takes only 1 second from canceling alarm silence to resuming alarm sound .

Long press of Display View ”

” key to enter into the Setup Menu screen, and move the cursor to each parameter (such as SpO2,

NIBP…) to make the high/low limit setting.

Limits setup: Move to the High or Low limits of the alarm settings, and press the “Alarm” silence key to turn ON or OFF the alarm for the setting. The alarm silence indicator will reflect this with a yellow light showing that alarms are silenced.

User Manual for Vital Signs Monitor (VET) Refer to Chapter 11.2 for detailed default alarming values of all parameters and setup range. Whenever the monitor is used, check the alarm limits to ensure that they are appropriate for the
patient being monitored. When mains power supply is lost for not more than 30s, the alarm settings prior to the power
interrupt will sustain or be restored automatically. 5.5 Verifying Alarm Function To verify the effectiveness of the alarm function, set the monitor working at “Demo” mode in system parameter settings menu. Adjust the alarm limits or change alarm setting, then pay a close attention to the alarm signal. If the visual and audible alarm indications appear according to your setting, it means the alarm function is effective. Do NOT set the alarm volume lower than the background noise.

Chapter 8 Monitoring Parameter
8.1 NIBP Monitoring
8.1.1 Measuring Principle
Blood pressure may be measured in an invasive way (whereby the sensor will be inserted into blood vessel directly) or a non-invasive way. The non-invasive way includes several methodologies, such as the Korotkoff Sound Method and oscillating method. The Korotkoff Sound Method is used as a conventional way, whereby stethoscope is used to measure the blood pressure. By the oscillating method, an inflation pump will fill the air, and release it slowly. A computer will record change of the cuff pressure when the air is released. With this record, the blood pressure value will be determined. First of all, make sure the signal quality judgment by computer meets the requirements of accurate calculation (such as sudden limb movement or cuff being hit during the measurement). If the answer is negative, give up the calculation. If the answer is positive, proceed with calculation of the blood pressure value.
As change of the blood pressure is recorded by electric sensor, which sensitivity is much higher than that of human ears, the oscillating method uses different definitions for measurement of diastolic pressure, mean arterial pressure and systolic pressure from the Korotkoff Sound Method. When the oscillating method is used, the circuit in the measuring apparatus will separate the amplitude of the cuff pressure from its change with pulsation. With the oscillating method, the blood pressure at the maximum amplitude of cuff pressure is defined as the mean arterial pressure. The blood pressure at amplitude of cuff pressure forward reduced according to proper proportion is defined as systolic pressure, while the blood pressure at amplitude of cuff pressure backward reduced according to proper proportion is defined as diastolic pressure. The maximum change of pulse pressure occurs at these two points. They are equivalent to the point with pulse sound and the point without pulse sound respectively in the Korotkoff Sound Method.
When the risk of invasive monitoring method outweighs its advantage of accuracy, non-invasive monitoring method shall be used.
Comparison between blood pressure measuring methods
To overcome the effect of human hearing variation and air release speed on measurement accuracy when the conventional Korotkoff Sound Method is used to take measure of blood pressure, people have been dedicated to study of automatic measurement of blood pressure. By now, automatic blood pressure measuring system based on the principle of oscillating method is mature. In practice, however, various problems are encountered, such as why the measures taken by the oscillating method is lower or higher than those taken by Korotkoff Sound Method? Why the measures are inclined to decline? Why, in some cases, no result is obtained in spite of the inflation actions? Why the measure values have big discreteness and even abnormal data in some cases? Why the SpO2 waveforms may disappear suddenly? …and so on. The following explanations are devised to give the answers.
The Oscillating method vs. the Korotkoff Sound Method
Blood pressure measurement by the oscillating method and Korotkoff Sound Method has good correlation with the invasive measurement. Notwithstanding, any of the non-invasive blood pressure measurements has its one-sidedness when it is compared to the invasive measurement. The oscillating method has its advantages over the Korotkoff Sound Method in less error, higher reliability and stability. Their differences may be reflected in the following aspects.
1.The measures by the Korotkoff Sound Method are liable to effect of human factors. For example, different people may have different sound judging ability, or different reactivity when listening to heart sound and reading mercury meter. The air release speed and subjectivity may also affect the judgment. By the oscillating method, the computation is accomplished by the computer, thus relieving the possibility of effect due to human factor.
2.With the Korotkoff Sound Method, the measure is taken on the basis of appearance and disappearance of heart sound. The air release speed and heart rate may have direct effect on the measurement accuracy. It also has the disadvantages of rapid air release and poor accuracy. In the contrast, with the oscillating method, the determination is calculated on the basis of cuff pressure oscillatory waveform envelope, and the air release speed and heart rate has little effect on the measurement accuracy.
43

User Manual for Vital Signs Monitor (VET)
3.Statistics show that, when measuring the hypertension, the measure taken by the oscillating method is likely to be lower than that taken by the Korotkoff Sound Method. When measuring the hypotension, the measure taken by the oscillating method is likely to be higher than that by the Korotkoff Sound Method. But, it doesn’t mean the advantages or disadvantages between the oscillating method and the Korotkoff Sound Method. Comparison with the results taken by more accurate method, let’s say comparison of the invasive pressure result with the output value by the blood pressure measuring simulator, will show which method has more accurate results. In addition, higher or lower value should be a statistical concept. It is recommended those used to adopt the Korotkoff Sound Method use different physiological calibration for values determined by the oscillating method.
4.The studies have shown that the Korotkoff Sound Method has the worst accuracy when it comes to measurement of hypotension, while the oscillating method has worse accuracy when it comes to measurement of controlled hypertension relief.
8.1.2 Factors affecting NIBP measuring Select a cuff of appropriate size according to the size of the subject. Prior to use of the cuff, empty the cuff of any residual air inside it to ensure accurate measurement. Locate the cuff in such a way that the mark “” is in the position where artery pulsates clearly for best effect. The lower part of the cuff should be 2cm above the elbow joint. Do not wrap the cuff over thick clothing; The patient should lie in bed or sit in a chair, in order for the cuff and heart to be at the same level and the most accurate measurement to be taken. Other postures may lead to inaccurate results; During measuring, do not move the arm or the cuff; The measuring interval shall longer than 2 minutes, in continuous measurement, too short interval may cause arm extrusion, blood quantity increases, then cause blood pressure increases. Keep the patient still and calm before and during measuring as the patient’s state also affect the measuring result, e.g. when excited or anxious, their blood pressure will go up. Results will also be affected by the time of day, tending to be lower in the morning and higher in the evening;
8.1.3 Clinical Limitations and Contraindications
1. Serious angiospasm, vasoconstriction, or too weak pulse.
2. Extremely low or high heart rate or serious arrhythmia (especially auricular fibrillation) will lead to unreliable measurements or an inability to take a reading.
3. Patients connected to an artificial heart-lung machine.
4. Patient taking diuretics or vasodilators.
5. With patient suffering from major hemorrhage, hypovolemic shock and other conditions with rapid blood pressure change or when the body temperature is too low, the readings will not be reliable, as reduced peripheral blood flow will lead to reduced arterial pulsation.
6. patient with hyperadiposis;
In addition, statistics show that 37% people report blood pressure difference of no less than 0.80kPa(6mmHg) between the left and right arms, and 13% people report difference of no less than 1.47kPa (11mmHg).
Note: Some practitioners may report big discreteness or abnormal value of the blood pressure measures when the oscillating method is used. As a matter of fact, the so-called “big discreteness” must be a term in the sense of statistical significance of mass data. Abnormal data may be observed in some individual cases. It is normal in the scientific experiments. It may be caused by an apparent reason, or by an unknown factor in some cases. Such individual doubtful experimental data may be identified and eliminated using the special statistical technique. It is not a part of this manual. The practitioner may eliminate the apparently unreasonable data according to the experience.

User Manual for Vital Signs Monitor (VET)
8.2 SpO2 Monitoring
8.2.1 Measuring Principle
Based on Lamber-Beer law, the light absorbance of a given substance is directly proportional with its density or concentration. When the light with certain wavelength emits on human tissue, the measured intensity of light after absorption, reflecting and attenuation in tissue can reflect the structure character of the tissue by which the light passes. Due to that oxygenated hemoglobin (HbO2) and deoxygenated hemoglobin (Hb) have different absorption character in the spectrum range from red to infrared light (600nm~1000nm wavelength), by using these characteristics, SpO2 can be determined. SpO2 measured by this monitor is the functional oxygen saturation — a percentage of the hemoglobin that can transport oxygen. In contrast, hemoximeters report fractional oxygen saturation ­ a percentage of all measured hemoglobin, including dysfunctional hemoglobin, such as carboxyhemoglobin or metahemoglobin.
8.2.2 Sources of interference for SpO2 Measurement
Intravascular dyes such as indocyanine green or methylene blue Exposure to excessive illumination, such as surgical lamps, bilirubin lamps, fluorescent lights, infrared heating lamps, or direct
sunlight. Vascular dyes or external used colouring products such as nail polish or tinted skin care Excessive patient movement Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line Exposure to a high pressure oxygen chamber Arterial occlusion proximal to the sensor Blood vessel contraction caused by peripheral vessel hyperkinesias or decreasing body temperature
8.2.3 Pathological reasons for low SpO2 measurements
Hypoxemia, functional lack of HbO2 Pigmentation or abnormal oxyhemoglobin level Abnormal oxyhemoglobin variation Methemoglobin disease Sulfhemoglobinemia or arterial occlusion exists near sensor Obvious venous pulsations Peripheral arterial pulsation becoming weak Insufficient peripheral blood supply
8.2.4 Clinical Limitations As the measurement is taken on the basis of arteriole pulse, a substantial pulsating blood stream is required. For a patient with weak pulse, perhaps due to shock, low ambient/body temperature, major bleeding, or use of vascular contracting drugs, the SpO2 waveform (PLETH) will decrease. In this case, the measurement will be more sensitive to interference. For those with a substantial amount of staining dilution agent (such as methylene blue, indigo green and acid indigo blue), or carbon monoxide hemoglobin (COHb), or methionine (Me+Hb) or thiosalicylic hemoglobin, and some with icterus problem, the SpO2 readings may be inaccurate. Drugs such as dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor resulting in serious SpO2 measurement errors. As the SpO2 value serves as a reference value for judgment of anemic anoxia and toxic anoxia, the measurement result of some patients with serious anemia may also present as good SpO2 value.
8.2.5 Points to be noted in SpO2 and Pulse Measuring
The finger should be properly placed (see the illustration to follow in this instruction manual), or else it may cause inaccurate measurement results.
Make sure that the sensor is lined up so the red and infrared LEDs pass through the capillary arterial vessels .
45

User Manual for Vital Signs Monitor (VET) The SpO2 sensor should not be used at a location or limb with an arterial or blood pressure cuff attached or receiving
intravenous injection. Do not fix the SpO2 sensor with adhesive tape, which may result in venous pulsation and consequential inaccurate
measurement result of SpO2. Make sure the optical path is free from any obstacles such as adhesive tape. Excessive ambient light (such as fluorescent lights, infrared heaters and direct sunlight) may affect the measuring result. Strenuous activity of the patient or extreme electrosurgical interference may also affect the accuracy. Please do not use the SpO2 sensor when having the MRI, or burn may be caused by faradism. Always observe the plethysmogram (waveform), which is auto-scaled within the range of 100. If the waveform is not smooth
or is irregular, this may indicate that the SpO2 readings are not accurate. If in doubt, rely on your clinical judgment, rather than the monitor readout. A functional tester cannot be used to assess the accuracy of the pulse oximeter monitor or a SpO2 sensor. However, a functional tester, such as SpO2 simulator can be used to check how accurately a particular pulse oximeter is reproducing the given calibration curve. Before testing the oximeter, please determine that the appropriate calibration curve is being used. If necessary, request this from the manufacturer and download it into the test device.
Chapter 9 Troubleshooting 9.1 No Display on the Screen Shut down the monitor and unplug the power. Use a universal meter to check whether the outlet has proper voltage, if the power cable is in good condition, and that the power cable is properly connected with this apparatus or outlet. Remove the fuse from the back cover of the monitor, and make sure it is in good condition. 9.2 No Blood Pressure and Pulse Oxygen Readings
1. Check that the blood pressure cuff is properly wrapped around the arm according to the operating instructions, that the cuff does not have a leak, that connections are secure on the cuff and tubing and that the inlet is closely connected with the NIBP jack on the side panel. Check that the LED of SpO2 probe flashes and that the pulse oxygen probe is properly connected to the SpO2 jack on the side panel.
2. If the problems still exist, please contact the local dealer. 9.3 Blank Print-out
1. Check whether the printing paper is installed the right way around (i.e. with the sensitive side upwards). Please reinstall it if necessary.
2. If the problems still exist, please contact the local dealer. 9.4 System Alarm
1. When the parameter value is higher or lower than the alarm limits, the alarm will sound. Please examine the condition of the patient and check whether the alarm limit values are set appropriately.
2. Probe off. Please check the connection of the probes.
