Estimated Oxygen Variation

[Phil_GT]

Hi there

I've found something in my fitbit app which i hadnt come across before.

The Oxygen Variation when it comes to sleeping.

Im not really sure how to use the information on there, there is a orange section that looks like a spike.

Does that mean i have too much Oxygen in my blood or not enough, little confused as there aren't any value's to make sense of it

If it matters, using a Charge 3

Thanks

Phil.

I'm sorry that no one responded until now.  My background is physiology and agree that this graph is very confusing.  But the explanation that "high variations can be linked to breathing issues" seems to indicate a lower than normal oxygen level.  I think it's a little over dramatic to say "not enough" when the graph has no values attached to it.
