HandHeld Pulse Oximeter
The normal range varies by individual, but usually over 95%, otherwise, please consult your physician.
What's the normal range of PR(pulse rate) value for healthy people?
Usually, the normal range is 60bpm~100bpm.
Why do the display value of SpO2 and PR vary with time?
Do not shake the finger, and keep calm during the measurement. Please also avoid the Oximeter and the cuff on the same limb for blood pressure and oxygen saturation measurement simultaneously.
Remove the batteries immediately and dry the Oximeter completely with a hair dryer.
Hold breath for a while (50 seconds or more), if the SpO2 value significantly decreases, it means that the SpO2 reading truly reflects the physiological condition change.
