The intensity of my sleep apnea varies from night to night, and you might be similar?

Based on oxygen levels, mine also varies from subclinial to "medium" apnea. I was deemed not to have sleep apnea based on the take-home test or the in-hospital test... but I wore my oxygen-logging ring during the in-hospital test to check it was calibrated to the hospital's equipment (it was), and the specialist then diagnosed me based on my measurements of oxygen levels on other nights.

Oxygen saturation is something of a red herring when it comes to sleep apnea diagnosis. Sure, having significant desaturation (<85%) is not good for you. But what will really wreck you is the arousals. Someone here mentioned an AHI of 70, that doesn't just mean you're not breathing right seventy times per hour, it also means you're waking up seventy times per hour. With that many arousals, your saturation might not budge all that much, but you're basically not getting any sleep at all.

And while we're on the subject, AHI is also pretty terrible. You could have an AHI of say, 5, which means "you don't have sleep apnea", but if you're sleeping 8 hours and these events only occur during the 2 hours of REM, then you've got an AHI of 20 during REM sleep, which will still wreck you.

What brand is your ring? I know some doctors that would love that!

Likely an Oura Ring: https://ouraring.com/

It sounds like one of the better sleep trackers (and not just sleep) if you aren't bothered by the whole "send detailed and continuous personal information to the cloud" thing. I'd recommend staying away from that kind of thing, though..

I have a "Wellue Checkme O2 wrist oxygen monitor". (The Oura ring didn't measure blood oxygen back then.)

What are O2 levels that suggest sleep apnea?

This page has some really good info: https://www.beverlyhillstmjheadachepain.com/sleep-apnea/puls....

It appears that going below 94% 5 times per hour would indicate mild sleep apnea.
