Suunto 9 Peak Pro
Normal blood oxygen levels are between 96% and 99% at sea level. At high altitudes, healthy
values can be slightly lower. Successful acclimation to high altitude makes the value increase
again.
How to measure your blood oxygen level:
1. From the watch face, press the middle button or swipe left to enter the Blood oxygen
widget.
2. Select Measure now.
3. Hold your hand still while the watch is measuring.
4. If the measuring failed, please follow the in-watch instructions.
5. When the measuring is complete, your blood oxygen value is displayed.
You can also measure your blood oxygen level during your 6.7. Sleep.
