Inspire 3 - No Unit on estimated oxygen variation

[arirangz]

Hello,

I am based in France and I am using the Inspire 3.

In the app, I can see the graph showing the SPO2 variation but there is no unit on the graph so it's hard to what values he have for that night.

I exported the values from my profiles and I can see the spo2 is collected every minutes, so recording works fine.

Is it possible to add units on the oxygen variation screen ?
Also is it possible to change the settings to record spo2 every 30 seconds?
And last question, in the spo2 CSV, I can see a lot of line with 50 as value. I guess this is when the device could read the value? If so, should I tight more the bracelet?

Thanks

Hello @arirangz and welcome to the Community.  I hope I can explain this concisely.  Reporting SpO2 is a medically regulated feature, so Fitbit needed US Food and Drug Administration approval to be released here.  Fitbit put the first SpO2 sensor on the Ionic (2017), but couldn't activate it. Fitbit created and released the Estimated Oxygen Variation (EOV) graph in 2020.  Getting your SpO2 from a wearable was a big deal at the time.  Fitbit created this graph, but couldn't put numbers on it.  It didn't have FDA approval to do that.  After Fitbit got FDA approval, it decided to give users average sleeping SpO2.  Fitbit never explained why it didn't add the values for the graph.  I'm not a Fitbit employee, so it might have involved more work to get FDA approval for that.

The EOV graph has been available for four years now.  Based on my personal experience, I don't think Fitbit will change it.  You can give feedback by voting for and leaving a comment in this request in the Product Feedback forum.

I never downloaded my SpO2 data, so I can't explain your lines with 50 as a value.

Hello @LZeeW 

Thank you for your very detailed answer. Ok I understand better the issue.

By experience, do you know approx what could be the scale of this graph ? Is it from 80% to 100% ?

Do you know any other app where I could import Fitbit data to visualize spo2 graph?

Thanks

@arirangz   There is no rhyme or reason to the graph.  I don't know of any app where you can import your Fitbit data to visualize a graph.  I also want to emphasize Fitbit's own statements on its SpO2 data.  It is for general wellness only and shouldn't be used to make medical decisions.

@LZeeW yes sure I understand that we can't take data for granted.

But as they are collecting the data, would be nice to have a nice way to visualize it. Otherwise it's not very useful.

When I exported the data, I could see all the spo2 for each minute of the night.

Thanks for your feedback.
