Does anyone know the degradation in blood oxygen levels under moderate exercise for a person who is fairly health (not athlete but slim, does regular exercise)?

Does anyone know the degradation in blood oxygen levels under moderate exercise for a person who is fairly health (not athlete but slim, does regular exercise)?
I had covid, so bought one of these, and I'm now building my way back to being able to jog, after months of shortness of breath. I would like to be able to understand what level my blood oxygen %, for a normal, healthy person, would drop to when say jogging.
- spaetzleesser 6y agoMine doesn’t drop much during exercise.
- amiga_500 6y agoDefine much, please. I believe getting near 90% at rest means it's time to think about an ER visit.
- peripitea 6y agoFrom what I understand, this is more because having that low of oxygen at rest is highly likely to be a symptom of a deeper problem, not because the 90% oxygen by itself is a huge imminent problem. Afaik you can go days/weeks at that level and be mostly fine if you are otherwise healthy. For example, this paper suggests that some people who live at high altitudes have perpetual SpO2 of <90%: https://www.thelancet.com/journals/langlo/article/PIIS2214-109X(19)30543-1/fulltext https://www.thelancet.com/journals/langlo/article/PIIS2214-1.... For those of us living near sea level, temporary drops below 90% should be ok if you are otherwise healthy (up to a certain point of course), because as someone else in the thread suggested, they will rebound to >=95% as soon as you return to rest/normal breathing. (Disclaimer: I'm not a medical expert, but have had to study breathing a fair amount. Happy to have corrections from anyone with more knowledge on this!)
- pps43 6y agoIf I really push during my 5k run, pulse oxymeter shows around 85%. Not sure how much to trust it, as soon as I stop it climbs back up. Unclear if it's due to vibrations, or my lungs catching up.
- amiga_500 6y agoMine starts beeping at 93% (if I hold my breath for as long as I can it drops to around 92%). My level does rebound again after a few seconds. 85%, sounds a bit low, not totally incredulous though.
