Fitbit range of products have a new upgrade – the Estimated Oxygen Variation Graph.
Not too long ago, Fitbit launched the Versa 2 and their new OS that provided a host of features and tweaks to their range of products now adds their new Estimated Oxygen Variation graph available to all Charge 3, Ionic, Versa, Versa Lite, and Versa 2 users.
This new feature, which began rolling out to some users in January, utilizes the red and infrared sensors on the back of the device to estimate the variability in your blood oxygen saturation level.
The graph, which users can see in the Fitbit app under the Sleep tile, approximates the changes in your blood oxygen saturation while you sleep.
Blood oxygen saturation measures the percentage of your blood that’s saturated with oxygen. Typically, it’s at 95-100%, meaning the blood is carrying as much oxygen as it can. If you stop breathing or have other lung issues, the saturation level can fall since less oxygen enters the body.
In general, variations should be low and seeing frequent, big variations could be a sign that you may be experiencing breathing disturbances during sleep.
The graph is another example of Fitbit’s commitment to providing more useful data to users. While extremely useful in monitoring your health, it is not intended for medical purposes and does not replace a medical examination.
