Finger Pulse Oximeter SPO2 PR PI RR Blood Oxygen Saturation Meter Heart Rate

1.Display parameters:
(SpO2) oxygen saturation measurement range: 70-99% measurement accuracy: 70%-90% ± 2%. If the value is below 94%, Insufficient oxygen.
(PR) BPM measurement range: 30 bpm – 250 bpm.
(PI) measurement range: 0.2%-30% , PI means Perfusion Index, it shows Blood perfusion ability.
(RR) Respiratory Frequency Detection-Normal Adult Breathe 16-20 Times Per Minute. Respiratory pulse ratio is 1:4, each one breath, four pulse beats. Normal child breathe faster than adult, breathe 20-30 times per minute, newborn could breathe 44 times per minute.
