Sleep and Oxygen?

[wadhalji1]

Am I missing it but I can't seem to get any full details on Oxygen. It shows a graph and like an average but not the drops and what the number is. Found out my oxygen has hit the low 80s and my watch NEVER shows this.

If fitbit doesn't give full details, does anyone recommend any other good devices like a smart watch that details this stuff better? Preferably no subscriptions.

Hi @wadhalji1 - Spo2 shown in the Health Metrics in the Fitbit App is an average oxygen level for the night.

You may get a range by going to the Today app in older Fitbit models on the watch or using a more performant clock face to get it on a Sense 2 if one is available.

The watch doesn't support all day or on the spot oxygen levels.

Hi @wadhalji1   Fitbit has three clock faces that will show your sleeping SpO2 range in addition to the average that is in your Health Metrics and available as a Today stat.  They are SpO2 Signature, SpO2 Blue, and SpO2 Stack.

You aren't missing anything in the EOV graph.  As a physiologist, I can share my thoughts on this graph, but don't have direct Fitbit knowledge.  To start, Fitbit must have FDA approval to provide SpO2 data.  Fitbit put its SpO2 sensor on the Ionic (2017), but didn't activate it on any device until early 2020.  Fitbit didn't have FDA approval to report the SpO2 data, so it created the EOV graph.  IMO, Fitbit wanted to report something to users.  Trust me, there is no graph like this in 'real' physiology.  Fitbit started reporting sleeping SpO2 data later in 2020.  I don't know why Fitbit never applied for the approval to add numbers to the EOV graph.
