The SpO
2
probe accompanying with the monitor is only intended for use in this monitor. The monitor can
only use the SpO
2
probe supplied in this manual. It is the operator's responsibility to check the
compatibility of the monitor, probe and extension cord before use, to avoid the patient's injury.
NOTE:
l
SpO
2
waveform is not proportional to the pulse volume.
l
Some models of functional tester or patient simulator can measure the accuracy of the device that
reproduces the calibration curve, but it can not be used to evaluate the accuracy of this device.
l
SpO
2
function is calibrated to show functional oxygen saturation.
l
The accuracy of pulse rate has been verified by using a patient simulator.
l
The PLETH waveforms are not normalized, so the accuracy of the measured values may decrease when the
waveform does not tend to be smooth and stable. When the waveform tends to be smooth and stable, the
measured value is the best value, and the waveform is the most standard.
l
The update time of measurement data is less than 10 seconds, which depends on the PR value. Data
averaging and other signal processing have no effect on SpO
2
displaying and data values transmitted.
l
The device does not need to be calibrated during maintenance.
12.3 SpO
2
Measurement
1.
During measuring, make sure that the wearing parts meet the following conditions:
u
Pulsating blood flow, and circulation perfusion is well.
u
The thickness does not change, the thickness change will cause the mismatch for the sensor and wear
parts.
2.
PR will be displayed only under the following situations:
n
Select "HR FROM" as "SpO
2
" or “BOTH” in the ECG SETUP menu.
n
Select "HR FROM" as “AUTO” in the ECG SETUP menu and there is no ECG signal.
NOTE:
l
Make sure the fingernail covers the light.
l
The SpO
2
value is always displayed in a fixed place.
l
The declaration for SpO
2
accuracy is supported by a clinical study covering the entire range.
12.4 Monitoring steps
1. Switch on the monitor.
2. Insert the sensor plug into the SpO
2
jack.
3. Attach the sensor to the appropriate site of the patient finger.
