characteristic:
Wrist design, small size, light weight; Blood oxygen saturation and pulse rate value display; Pulse wave and nasal airflow waveform display;
Low power alarm, blood oxygen finger clip falling off, pulse rate over limit alarm can be set; Automatic switching on and off;
Multi case storage;
Continuous data storage for 20 hours; Upload USB data to PC; Software analysis of upper computer;
Use app to realize remote communication.
Electrical parameters:
Measurement range of nasal airflow: measurement range: 0-40 times / minute;
Branch office rate: 1rpm resolution:lrpm;
Error rate: 2rpm accuracy- 2rpm;
Measurement range of blood oxygen saturation:
Measurement range: 0% - 100%;
Resolution: 1% resolution:1%;
Error: when the measurement range of blood oxygen saturation is 70% - 100%, the allowable absolute error is 2%, and there is no definition when it is less than 70%;
Pulse rate measurement range:
Measurement range: 30-250 BPM (times / minute); Minute rate: 1 BPM;
Error rate: 2bpm or 2% (whichever is the maximum);
Anti ambient light interference ability of blood oxygen measurement: the blood oxygen measurement value under indoor natural light and current phase light source is compared with the measurement value under laboratory conditions,
The deviation is less than 1%.
