Blood oxygen unrealistic reads?
-
It’s normal, the optical sensor is not for medical usage, if you want accurate value, finger sensor is a better choice
-
my S9P reading most of the time are below 94% while my finger sensor are in between 95% to 99% when read at the same time.

@zhang965 Ok. Thank you! As a follow up, are any of the other measures based on this read, I.e. VO2Max, fitness level?
-
@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
-
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
-
@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.
-
@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 now
️ what to do? -
@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.
