Blood oxygen unrealistic reads?

[isazi]

@Neurunni is this at night, or also with manual measurements? My protocol for manual measurements is very still, arm on the table in from of me, and I usually get good measurements. Anyway I do not use this feature for health (the watch is not a health device), just when at altitude (morning during breakfast and evening during dinner).

@Neurunni no other metric uses SPO2 as input, for what I know.

Apple Watch infringed on Masimo patent, judge rules, raising prospect of import ban

lol just read it

[Neurunni]

Obviously I’m not using it for medical purposes for myself or anyone else, i was simply curious if it’s normal for my watch to show me inaccurately that my lungs are dying is all.
Thanks for the replies.

@isazi do you happen to know what the VO2Max uses? It’s a formula & wondering if it’s based off of HR only

[isazi]

@Neurunni well it shouldn’t give such horrible measurements, that’s why I asked if it was during the day or at night you got them.

[isazi]

@Neurunni should be pace and HR only, I don’t have the exact formula of the Firstbeat VO2max algorithm Suunto is using.

@isazi both day and night and both measuring it &the automated measure. I’ve had it for 2 weeks now‍️ what to do?

[Neurunni]

@isazi thank you!

@Neurunni
I would recommend to try different strap “settings”. I am used to wear my watch lose, but tighter settings of the strap will improve sensor measurement quality.
maybe you already wear it tight enough, but just mentioning it as a potential improvement

@freeheeler In fact, at least for me, the current strap has made the big difference, now giving me consistent results. also, be careful to stand still during measurements.
