What is Blood Oxygen (SpO2) Tracking on my CZ Smart watch?
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.
