Does this blood O2 indicate apnea?
Does this blood O2 indicate apnea?
Hi there! I'm still at the stage of trying to figure out whether my sleep issues might be due to apnea. I wear an Apple Watch to track my sleep and it also tracks blood oxygen levels. My levels frequently dip down to around 80% at night, although they generally stay at over 95% during the day. I know the watch isn't a medical device, but could this be an indication that I need to look into apnea as a possible cause?

Symptoms: No trouble falling asleep but I wake up too early after around 4-5 hours and generally can't fall asleep again. When I wake up like this I feel like I've just drunk a couple of strong shots of espresso. As a result I feel sleep deprived most of the time, which is getting to be really an issue. 

Thanks in advance for any tips.  Smile

I was diagnosed with OSA in the basis of just a finger oximeter session. My 02 plummeted several times an hour and my pulse would race to compensate. I was fast-tracked onto an APAP machine immediately. So yes, it is possible to diagnose OSA on the basis of oximetry. But I would strongly recommend you get a professional diagnosis and, preferably, an overnight sleep study, so you know what you're dealing with.

Welcome to the forum!

I've advised someone who was interested in having a sleep study done to measure blood oxygen levels. They were normal=for me, why worry.

I'm just a cpap user like you. I don't give medical advice. Seek the advice of a physician before seeking treatment for medical conditions including sleep apnea. Sleep-well
