Technical parameters of
blood oxygen pulse rate:
Blood oxygen saturation
Blood oxygen saturation measurement range: 0%~100%
Blood oxygen saturation display resolution: 1%
The accuracy of blood oxygen saturation measurement: in the
range of 70% ~100%, the measurement error should be ±4%; in the
range of 0% ~ 69%, the measurement error is not defined.
Blood oxygen saturation alarm setting range: the upper limit of the
alarm should be 1%~100%; the lower limit of the alarm should be
0%~99%
Blood oxygen saturation alarm accuracy: the alarm accuracy should
not exceed ± 1% of the alarm setting value.
Technical alarm: there should be an alarm when the sensor falls off Pulse rate:
The pulse rate detection range should be 30bpm~240bpm
Pulse rate detection resolution: 1bpm;
The accuracy of pulse rate measurement should be ±3bpm;
Pulse rate alarm setting range: the upper limit of the alarm
should be 2bpm—254bpm;
The lower alarm limit should be
0bpm—252bpm
Pulse rate alarm accuracy: the alarm accuracy should not
exceed the set value ± 1bpm.
