8. Non-invasive Blood Pressure Test and Calibration

The accuracy of the NIBP reading of the monitor is decided by: NIBP calibration and themeasurement range of the blood pressure sensor. Correct testing and calibration methods are asfollows:

(1) Unplug all cables connected to the monitor except for the power cable.(2) Turn on the power switch of the monitor.(3) Connect the hose of the cuff to digital pressure meter, auto inflating bladder and NIBP socket

at the side panel of the monitor through a 3-way TEE. Inflate the cuff to a certain pressurelevel, compare the pressure reading on the digital pressure meter and the monitor screen to seeif their value difference are less than 3 mmHg. If not, you need to do blood pressurecalibration.

(4) Input a password and enter the system maintain menu as follows,

(5) Rotate knob to Pressure Compensation, select the value to be calibrated (-6 6mmHg orAuto), then exit the system calibration menu.

(6) Repeat (3) , if digital pressure meter and monitor screen have the same pressure value, thencalibration is complete. If not, re-calibration is required. If the same results cannot be obtained


3-5

through repetitive calibration, please contact manufacturer.

9. Speaker Test

(1) Turn on alarm sound and set Heart Rate alarm limits. Test if the monitor will make alarmsound when heart rate is outside alarm limits.

(2) Silence alarm sound and test if the monitor will make alarm sound when heart rate is outsidethe alarm limits.

(3) Turn on the alarm sound. Speaker test is complete.

10. Networking Test

After monitor is networked with the central station monitoring system, inspect if the ECGwaveform and its parameters will be correctly displayed on the central station monitoring system.

When the above tests are complete, turn off all the test devices and monitor and remove the testdevices away from the monitor.

F. Electric Safety TestElectric safety test inspects if the monitor has potential hazards to patients or operators.

In order to establish a systematic maintenance plan, we recommend all safety tests and recordsshall be made under the following circumstances: Upon reception of the monitor, every other year,and the monitor is opened for repair.

Caution: If hospital staff did not observe the maintenance plan, which leads to inaccuratemeasurement of the monitor or potential hazards to operators or patients, unless otherwise agreedby both parties, manufacturer shall not undertake any responsibilities. All responsibilities shall beundertaken by the user of the monitor.

Section 4 TroubleshootingA. Special Components

1 Surface Mounted DevicesSurface mounted devices are used to aid in miniaturizing the electrical assemblieswithin the monitor.

WarningSurface mounted components were not designed to be removed or replacedusing standard soldering equipment. Removal of surface mounted components using aconventional soldering iron can potentially destroy the PCB.Only soldering workstations specifically designed for surface mount technology maybe used to remove and replace these type of components.

B. Power Failure

1 No display after power onPhenomenon: When the monitor is powered up, there is no display on the screen

and LED does not light up.Inspection method: 1) Without connecting the monitor to AC power supply, check the

battery power level.2) When connecting the monitor to AC power supply, check the

connection between the power socket and the plug of themonitor, the power cable, and the AC output.

Solution: Make sure all connections are reliable and connect the monitor toAC power supply to charge the internal battery.

C. Data Received Trouble

1 No ECG waveformPhenomenon: When leadwires are connected, there is no ECG waveform. The

screen displays LEAD OFF or NO SIGNAL.Inspection method: Check ECG electrodes contact with patients skin and check all

leadwire connections.


4 - 2

Solution: 1) Replace ECG electrodes and clean the skin surface whereelectrodes are applied.

2) Resistance of 1k should exist between extension wiresapplied to patient body to the leads of the ECG connector. If itis indefinitely large, it shows that the leadwire is broken andshould be replaced.

3) If ECG waveform channel shows No signal received, then itshows there is some problem in the communication betweenECG module and the main system. If this message still remainsafter the monitor is turned off and on again, please contact thesupplier.

2 ECG Baseline ShiftPhenomenon: ECG baseline is not stable, occasionally shifts out of the display

area.Inspection method: 1) Check if the working environment is very humid and if the

monitor has moisture inside.2) Check if the electrodes quality is good, and the skin surface

where the electrode is applied is clean.

Solution: 1) Turn on the monitor and let it run for 24 hours to removemoisture inside.

2) Replace it with good electrode, clean the skin surface where theelectrode is applied.

3 ECG Waveform NoisePhenomenon: ECG waveform is too large, no entire frame of ECG waveform can

be seen.Inspection method: Check if the ECG scale is so high that it results in the ECG

waveform overflow.Solution: Adjust ECG scale to a proper level, normally 1.0mV or 2.0mV.

4 Electrosurgical interference on ECGPhenomenon: In the surgical operation procedure, the use of electrosurgerical

equipment will cause interference on ECG.Inspection method: Check the grounding condition of the monitor and the

electrosurgical equipment.Solution: Make sure the monitor and the electrosurgical equipment are

properly grounded.


4 - 3

5 Weak Respiration SignalPhenomenon: The respiration waveform is too low to examine.Inspection method: Check if the ECG electrodes are located correctly and if the ECG

electrodes contact with patients skin is well.Solution: 1)Apply the ECG electrodes as Fig. 4-2 in P4-5 show, clean the

skin surface where electrode is applied.2)Select other lead.

6 No SpO2 readingPhenomenon: In the process of monitoring, there is no SpO2 waveform and data.Inspection method: Check the finger probe to see if there is red light, if the arm is being

pressed, and if the room temperature is too low.Solution: If there is no red light in the finger probe, check the extension cable

and connecting part. When room temperature is very low, do notexpose patients arm outside , which will affect the measurementresults. Do not measure blood pressure and SpO2 on the same arm.Pressing the arm will affect SpO2 measurement.If SpO2 waveform channel shows No signal received, it indicatesthat there is a problem in the communication between SpO2 moduleand the main system. If, after turning the monitor off and on again,the message still remains, change the SpO2 board.

7 Intermittent SpO2 SignalPhenomenon: During SpO2measurement, the reading is off and on.Inspection method: 1) During prolonged monitoring and surgery, check if patient arm

movement results in interruption of SpO2 measurement.2) Check the SpO2 extension cable.

Solution: Keep the patient steady. It is normal if SpO2 value is lost due tohand movement. If SpO2 extension cable is faulty, replace it.

8 Abnormal NIBP readingPhenomenon: NIBP measurement result is abnormal.Inspection method: Check if the cuff leaks or the tube connector leaks.Solution: Replace it with good cuff and connector.


4 - 4

9 Low Inflation PressurePhenomenon: During blood pressure measurement, the inflation pressure keeps to

be low.Inspection method: Check if the NIBP cuff or extension tube is broken.Solution: Replace it with good NIBP cuff and extension tube.

10 Abnormal IBP ValuesPhenomenon: Displayed IBP values are different than expected.Inspection method: Check tubing for bubbles.Solution: Rezero the transducer.

11 Wrong displaying of IBP waveformPhenomenon: Displayed IBP waveform is not regular.Inspection method: Check if the cable is outburst.Solution: Replace good quality cable.
