I've been measuring o2 levels.
Varies between 99 and 95. Different reading each check. I'm sure variance is to do with other factors.
Mine is never below 96 during the day but drops at night (see below) down as far as 86% (albeit I only have two nights' data). Maybe I have some mild sleep apnea - I don't seem to have any problem with my sleep and I'm rarely ever awake during the night.
(Data is from a Garmin Forerunner 945 watch. Yes I wear it nigh on 24/7.)

What's it been on re checks?
