How do I measure blood oxygen with Suunto 9 Peak?

You can measure your blood oxygen levels with Suunto 9 Peak. The blood oxygen level can indicate overtraining or fatigue and the measurement can also be a helpful indicator of high altitude acclimation progress.

Normal blood oxygen levels are between 96% and 99% at sea level. At high altitudes, standard values can be slightly lower. Successful acclimation to high altitude makes the value go back up again.
