ECG Verification
Tools required:
Vernier caliper
1. Select the ECG parameter window or waveform area→Filter→Diagnostic.
2. Select Main Menu→Maintenance→enter the required password→Module.
3. Select Calibrate ECG. A square wave appears on the screen and the message ECG Calibrating is displayed.
4. Compare the amplitude of the square wave with the wave scale. The difference should be within 5%.
5. After completing the calibration, select Stop Calibration.
If necessary, you can print out the square wave and wave scale through the recorder and then measure the difference.
4.4.2 Resp Performance Test
Tools required:
Medsim300B patient simulator
1. Connect the patient simulator to the module using a non ESU-proof cable and set lead II as the respiration lead.
2. Configure the simulator as follows: lead II as the respiration lead, base impedance line as 500 Ω; delta impedance as
1 Ω, respiration rate as 20 rpm.
3. Verify that the Resp wave is displayed without any distortion and the displayed Resp value is within 20±1 rpm.
4.4.3 SpO
2
Test
Tools required:
None.
1. Connect SpO2 sensor to the SpO2 connector of the monitor. Set Patient Category to Adult and PR Source to SpO2
on the monitor.
2. Apply the SpO
2
sensor to the ring finger of a healthy person.
3. Check the Pleth wave and PR reading on the screen and make sure that the displayed SpO
2
is within 95% and100%.
4. Remove the SpO
2
sensor from your finger and make sure that an alarm of SpO
2
Sensor Off is triggered.
Measurement accuracy verification:
The SpO
2
accuracy of the MPM module has been verified in human experiments by comparing with arterial blood
sample reference measured with a CO-oximeter. Pulse oximeter measurements are statistically distributed and about
two-thirds of the measurements are expected to come within the specified accuracy range compared to CO-oximeter
measurements.
