Blood oxygen on Watch 5 is pants !

[Bex8]

It would seem I pretty much die every night since upgrading to the watch 5.

Blood oxygen dropping to below 70 every night . I am a healthy person, and I am wearing my watch correctly . Anyone else have this problem ?

That's a worry!

I am on my 3rd 5 pro Lte, my second one, couldn't record O2 levels at all..
Obviously I don't know whether right or wrong.. 1 It's working, 2 Numbers seem generally OK.

I had the same issue on the watch 4 dips in the 60/70s I got a referral to a sleep apnea clinic and my results are fine. Just another gimmick and clever marketing these smart watches are not that smart, which is why I never upgraded, absolutely no point its just a glorified step counter with some bells and whistles.

Edit:-
For transparency I think the bpm is fairly accurate but so is a Chinese bpm/spo2 meter that you stick on your finger and those are cheap as chips

I posted a similar topic a few months back, I always wear my watch 5 and 4 prior 247, I was snoring loudly after seeing a consultant and have and overnight full on spo2 device, he said I never had a single episode, that said my Watch Pro was say I was regularly 15 plus minutes below 70%.

So is the watch 5 pro a waste, err no, like the BP, BMI, etc... its a useful directional trend indicator that's about it.

I said that as after having an operation for a deviated septum, I am now always towards 99 to 100%, maybe minor episodes, but I think there is a clinical definition of sleep apnea and time below that is regarded as and issue or not.

I have the Samsung watch 5 and I have been getting some terrible Blood Oxygen readings at night. Sometimes as low as 71 for a lot of the night. This would basically mean that I'm dying in my sleep and I should wake up feeling awful, but I don't at all, I feel perfectly fine...

When I look it up, there are so many people saying how accurate the readings are and that they picked up real sleep apnea issues thanks to their watch. So I have been concerned.

I bought my bf a galaxy fit watch for Xmas and his BO readings are really good. So I used it to put my watch to the test. I slept with both watches on last night and got totally different readings. Mine showed the usual "dying in my sleep", and his showed that my BO was above 90% all night 😅. Whew!
