How do I measure blood oxygen saturation?

Open the Blood Oxygen Saturation app, and start the blood oxygen saturation measurement as instructed.

Precautions:

1) Wear the band one finger away from the wrist bone (prominent part of the ulna).

2) Wear the band tightly, with an appropriate sense of pressure.

3) Place your arm on a tabletop or a stationary surface, with the band screen facing up.

4) Remain still during measurement and focus on the measurement.

5) Factors such as hair, tattoo, shaking, low temperature, and incorrect wearing of the band may affect measurement results and even lead to measurement failure.

6) The measurement range of this band is 80%-100%. This feature is for reference only and should not be used as a basis for medical diagnosis. If you feel unwell, seek medical advice.
