- Blood oxygen saturation level, also indicated as SpO2, is a measure of the percentage of oxygen carried by your blood. A normal SpO2 level ranges from 95% to 100%. However, this may change, depending on different factors, such as current health conditions, altitude, or exercising. Maintaining a normal blood oxygen level is necessary since, in some cases, blood oxygen levels can be indicative of health problems.
- You can keep track of your estimated blood oxygen levels in the Gen 2 Wellness watch app, either by initiating a new reading or by allowing background readings.
- SpO2 measurements on your watch are not for medical use. Thus, please consult your doctor if you have any health concerns.
