I am comming back with some updates regarding sleep and VO2.
During the sleep the VO2 value seems to be in to an acceptable range:94-100. Let’s say up to some point, accepting tolerance plus my body health.
If I want, at request, to measure my blood Oxygen still is a totally mess.
The measurement takes tens of seconds, most of the time, the value is far away from reality, like in between 72-85. Only after 2-3 measuremnts i get something close to reality, if I manage to make make 2-3 measurement. Why? Basically is trying to measure like 30 seconds and then the watch is saying unable to measure. I position the watch as mention in Suunto manual, also on top of my arm, also I have try under the arm, having an hairy arm. Some behavior. Also arm in different position and trying not to move. Even that is workin randomly, most of the time I cannot have 2 consecutive good measurement.
How that during the sleep is working and at request not?
The syncronization regarding watch and phone is working right now, at least up to now.
Also the nap is summing during the day and I have a total slepp time for the entire day.
