You can track your blood oxygen levels with your watch in one of the following ways:
- Take a new reading:
- Open the Gen 2 Wellness watch app
- Select Blood Oxygen
- Tap “New Reading”
- Stay still until the reading completes!
- Allow background readings:
- Make sure that you enable both Sleep Tracking & Blood Oxygen Tracking in Wellness watch app
- Wear the watch to sleep for background SpO2 reading
Your watch tracks your blood oxygen levels by measuring the reflection of red, green, and infrared light signals coming from the back of your watch.
