4.2 Main Parameters
A. Measurement of SpO2
Measuring range: 0%~100％
Accuracy: When the SpO2 measuring range is 70%~100%,the
permission of absolute error is ±2%, Below 70% unspecified.
B. Measurement of pulse rate
Measuring range:30bpm~250bpm
Accuracy: ±2 bpm or ±2% (select larger)
C. Measurement of PI
Measuring range: 0%~20％
Accuracy: ±2 bpm or ±2% (select larger)
When the PI measure range is 1%~20%,the permission of
absolute error is ±1%
When the PI measure range is 0%~0.9%,the permission of
absolute error is ±0.2%;
D. Resolution
SpO2 : 1%, Pulse rate: 1bpm, PI: 0.1%
E. Measurement Performance in Weak Filling Condition
SpO2 and pulse rate can be shown correctly when pulse-filling
ratio is 0.4%. SpO2 error is ±4%, pulse rate error is ±2 bpm or ±2%
