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~250bpm;
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
Bluetooth module parameters
