Compatible with devices that have the Sp02 sensor.
We’ve reviewed a bunch of Fitbit trackers over the past few years and one of the dominant hardware features on some of their devices is a Sp02 sensor – though was mainly disabled and will only be enabled in a future update. Fast-forward to today and Fitbit is finally rolling out blood oxygen tracking by enabling that sensor, which should give you more data about your overall health.
Sp02 basically measures how much oxygen is in your blood that is represented by a percentage. It was said that 95-100 percent is considered normal while anything below that might lead to some serious health problems.
On the Fitbit app, you will now see a new graph called the Estimated Oxygen Variation that is found under sleep data. Fitbit says that data that was available from the red and infrared sensors on compatible devices help give out a reading of your blood oxygen level.
The feature is still rolling out to everyone, but users of the Fitbit Ionic, Versa, Versa Lite, Versa 2 and Charge 3 which all have Sp02 sensors should expect the update to roll out in the next few weeks.
