Technical parameters 

Blood oxygen saturation (SPO2)

Measuring range: 35%~100% Display range: 35%~99%

Measurement accuracy: 70%~100%: ±2%; 50%~69%: ±3%;

No requirement below 50% (where the percentage sign "%" is the pulse oximetry percentage)

Measurement accuracy: in the 70～100% measurement range, Arms≤3% (For the definition of Arms, please refer to the standard YY0784-2010)

Pulse rate (PR)

Measuring range/display range: 30bpm~240bpm;

Measurement error: ±2% or ±2bpm, whichever is greater

Perfusion Index (PI)

Measuring range: 0.2%～20%

Preset limit value

Prompt setting range when blood oxygen saturation exceeds the limit:

Lower limit prompt: adjustable within the range of 85%~99%, the default is 90%

Reminder range of pulse rate exceeding limit:

Upper limit: 100bpm～240bpm, the default is 120bpm;

Lower limit: 30bpm～60bpm, default 50bpm

Anti-interference

Anti-interference ability of natural light: When used in a natural light environment, the measured values of pulse oximetry and pulse rate meet the requirements of the above-mentioned standards.
