Estimated Oxygen Variation

[Den_in_USA]

Why is this now available on only some Charge 3 and Versas?

Hi, I assume by "actual O2 levels" you are referring to SpO2 which is SaO2 measurement determined by pulse oximetry. I would agree that a good percentage saturation number to tell your doctor would be useful to tell your doctor, however I suspect your doctor could measure it while you are there.

The novel feature of being able to graphically observe dramatic changes in relative O2 levels in a way to indicate that you have breathing interruptions seems totally unrelated to the magic number you seek. In fact, without medical tests for anemia (which affects blood gas measurements), the tightness of the band, external illumination, and numerous other factors there will be variations in absolute measurements making it unwise to depend on the single number you seek. The good news is that  SpO2 is noninvasive so it is safer and more pleasant for someone than invasive methods of oxygen analysis. 

It  seems far from being garbage to me. I certainly look forward to see how useful this approach actually becomes. What a wonderful time we live in.

I simply reply by email .... if that helps then it goes onto the community

I did a copy and paste

I was getting the oxygen variation graph on my versa 2, but it is no longer showing and previous graphs are gone.  Any suggestions?  

[SunsetRunner]

I would say contact support but you would be better looking around the
forum for answers

[RonaldM]

Support will not be able to help much because it's not rolled out formally. I know people here where able to get it to work again... 

[SunsetRunner]

I guess we will have to wait

[Crakie]

Thanks! I’ll look thru the forum and see what others have done or contact support.

[SunsetRunner]

Please let me no if you have any luck

The good news:

You can download your whole datafile (in your profile) in a .zip file, which I guess holds the whole data that fitbit has collected from you. Under it you'll find files named estimated_oxygen_variation-yyyy-mm-dd with all this data collected since the device purchase (in my case since 2018!). You can plot them in excel and see what I assume that will be included in the EOV graph that fitbit intends to roll out in 2020.

The bad news:

The number is a -100 to 100 figure which I assume just sets some variation below/above a 0 level of reference (whatever it might be). So,it seems to be useless as an absolute value of SPo2.

The worst news:

I correlated the numbers in this files with those from a pulseoximeter during the night, and I found  NO correlation at all (even taking into account the the time seems to be GMT). So, I'm puzzled and with many doubts about this data

Hope it helps.

Oh right the question is do I download them on my iPad / iPhone or just
wait for Fitbit

[BobHall]

just download the app, the EOV chart appears at the bottom of the daily sleep summary, below the sleep stages graph. Mine reappeared after being gone a while.

[SunsetRunner]

Oh right I installed the app when I purchased around December 17th and I’ve
updated to latest version and this is what I see on my sleep stages

[kelpiep]

Just wait for Fitbit. It’s been coming and going on my app. They must still be working on it. It’ll be there when it’s there...I don’t think we have any control over it on our end.

I wonder how many more years it will take.

[HobzyBobzy]

I noticed the estimated oxygen variation (EOV) recently, but 2 days ago (with the recent update), the graph disappeared, instead, I got two locked services "sleeping Heart Rate" and "restlessness" which you can unlock by going premium! I wonder, is EOV is there under one of those locked services or was it retracted? 

[SunsetRunner]

your guess is as good as mine

[SunsetRunner]

No it should be available to customers who own Fitbit charge 3 and versa /
versa 2

[Josepereh]

I'll just wait a week more to see if this data appear and if it is useful. If not I'll move to a VA4 from Garmin, though it is not the concept of tracker I actually want.

[SunsetRunner]

I think I might wait and see what Apple brings out later this year because they’ve been allowed to use the oxygen sensor this year
