Blood oxygen
-
@Piiipmatz For blood oxygen measurement (the way its carried by smartwatches), the watch needs a lot of conditions :
- low ambient light
- absolutely no movements
- resting state
which all happens pretty regularly at night, and is pretty hard to get by day.
Also, the watch seems to try to measure it multiple times during the night, and it gets 8ish hours to do so, so it can try many times too.The reflective Blood oxygen measurement is really shitty compared to transflective measurement (the one in the hospitals where the hook it to your finger), and smartwatch measurement are really not that great, as shown by the pretty bad accuracy and repeatability

Just curious. How can this metric help in structuring your workouts?
-
@cheetah694 For me it doesn’t structure my workouts, but I noticed it was a good indicator for altitude adaptation, and it helped “temper” my speed expectation on some trails
-
@Piiipmatz I have the same problem, but I believe that the measurements at night are incorrect.

we have a known issue about blood oxygen reporting very low values. If you have this please report the version you are on

@Dimitrios-Kanellopoulos 2.46.14

@Dimitrios-Kanellopoulos i have 2.46.14
Since last firmware update i notice every night Blood Oxygen is reporting around 92% before update it was usually 96-98%. And i am not able to measure manually. Tried many times in last days. Even tried soft reset. No change. Unable to measure manually.Update: after soft reset it is even worse, last night 88%, soon i will need oxygen mask
Update2: after rollback to 2.46.4 manually measures again, but results are low values. 88-93%, after 5th try i finally got 98% but since other 4 was around 90% it is hard to trust
Update3: two nights after rollback bloodoxygen worked and measured 96-98% rannge

I had problems before but with 2.48.16 it works fine. Did you tried soft reset?

@Eddy-De-Backer unfortunately, i tried to soft reset but it did not work for me.
