Good SPO2 at night?

[DougVK]

What level of SPO2 is good for sleep?

My average SPO2 at night seems to be 94% with some drops to 92 and some rises to 97%, with 94% being average. Awake it is around 95% on average, so only a sleep drop when asleep. I thought anything above 90% at night was good, but I was reading that it should be above 95%, so now I am confused. My average AHI is less 2, which I think is great considering how bad it was during the sleep study.

The higher the better, for the most part, but how do you feel? If you feel great, it's probably fine.

I feel fine so far, one slight concern I have is when I first started using the CPAP my average SPO2 at night with it was around 97%, my average awake SPO2 use to be around 98% too. Not sure if this slow decline in SPO2 over time is important though.

Just to be clear it was 97% with the CPAP when I first started, without the CPAP I would hit below 70% some times.
