Pulse rate alarm range: upper limit alarm: 160bpm; lower limit alarm: 60bpm

Pulse rate alarm error ±2% or ±2 bpm, whichever is greater

Perfusion Index (PI)

Measurement range: 0.2%～20%

Measurement accuracy: 0.2%~2% ±0.1%

                                       2%~10% ±1%

Anti-interference

Anti-interference ability of natural light: The deviation of the blood oxygen measurement value under indoor natural light and existing lighting source is less than ±1% compared with the measurement value under darkroom conditions.

Anti-artificial light interference ability: It can accurately measure the pulse oximetry value and pulse rate value under the test conditions of the pulse oximeter simulator.
