Fitbit Oxygen variation graph feature details
The Oxygen variation graph will be located in the Sleep tile. Here the user can check the graph that “approximates the changes” the in blood oxygen saturation level while sleeping. It is a measure of the percentage of blood that is saturated with Oxygen at any given time. This level should be 95-100 percent at any regular time. This means that the blood is carrying as much oxygen as possible. If one stops breathing or if they have any other respiratory issue, the percentage of saturation will fall. In general, the variation should be less with consistent changes. Also Read - Fitbit Versa 2 Review: A steady fitness companion
