What's the normal range of EOV?

Hi Versa 3 friends.  I'm new to this so little bit concerned. Checked my Oxygen saturation got 93% while sleeping, and last night's range 88%-96% 

Is this normal? 🤔

Hi there, @podkam. Thanks for stopping by in the Community Forums and the details provided in your post. I understand where your concern is coming from. 

Estimated oxygen variation (EOV) is an approximation of the changes in your blood oxygen saturation levels. Your blood oxygen saturation level is the percentage of your blood that’s saturated with, or contains, oxygen. Typically, your blood oxygen saturation level is between 95–100%, which means your blood is carrying as much oxygen as it can. The oxygen levels in your blood tend to remain relatively constant, even during exercise and sleep. If you stop breathing or have lung issues, your blood oxygen saturation level can fall as less oxygen enters your body (source).
