I would expect it to be high CO2 levels in the blood. Your SpO2 gets back to normal after not too long once you're awake and breathing normally, but CO2 levels remain elevated and reach a steady state level that is abnormally high.

I remember seeing a post here about room ventilation in schools and students performing better with a window open because of CO2 levels as well.

Hmmm. So I’ve been told I snore, and always have. I do apparently stop breathing at times. I got an Apple watch to monitor my oxygen levels and they don’t go below 90 when I sleep. But it may be high co2 that is the worry? Which the watch doesn’t test obviously. Great. I’m doomed. Also; breath holding as in swimming or diving, that could be doing brain damage?

Get a sleep study done. I did and only got 5 hrs of sleep because they’re always waking you up to adjust your mask and air pressure. Swear to God it felt like I slept for 12 hours. I’ve never felt more alert in my life without any caffeine.

I’m less anxious during the day. I have less nightmares. My cpap changed my life.

Hard second this. I'm 3 years into using mine. It puts me to sleep now.

Not breathing is what apnea means. Also, 90 is pretty low...

Seconding going to get a sleep study. The hassle of a CPAP is completely worth it if you have sleep apnea. That first week of sleep after getting used to the mask is glorious. You don't realize how exhausted and tired you are through the day if you aren't sleeping well due to apnea.

And unless you are spending man hours a day, every day, holding your breath for extended periods of time then no, you shouldn't be doing any quantifiable damage.

Sleep tech here - get a sleep study done! Your watch is not a doctor, but for sure providing you with info you could and should discuss with one.

I’ll ask my GP when I go in for labs next month.

I don’t rate the Apple Watch oxygen monitoring. It only samples about 10 times in a single nightly sleep period. I sometimes wear an oxygen monitor and it never correlates with the watch. I’m on CPAP too.


[deleted] t1_je253pz wrote

Hmmm. Ok. Good to know. Is there a setting to make it check more often?


Active_Remove1617 t1_je26hyq wrote

Nope. It’s a very poor attempt. Maybe in future updates.

Beh. That’s why I got the thing, really. To check my sleeping.


Active_Remove1617 t1_je2ek8i wrote

Me too. That and the ECG function.

Well don’t tell me THATS stupid too?

No,I hear that’s really good. Top class. This makes the O2 poor performance all the more lamentable. The o2 measuring is actually accurate but the sample rate is awful.
