Avg AHI <1 to 2.5 in a year

Reaching out to try and figure out what is going on and if this is stress/anxiety.

Male, 31, BMI <25, in moderate to good shape. Diagnosed with severe sleep apnea about 5 years ago (due to powerlifting?). Original equipment I had been using for ~ 4 years was CPAP set on 10. I slept perfectly with unit.

About a year ago switched to APAP 6-20. AHI was still less than 1 most nights, but slowly started creeping up over the course of a few months. Might have been noticing it more, because the new machine displayed AHI and my old one didn't.

I've noticed mainly central apneas that I haven't had in the past, so I wonder if I developed central apnea by switching to an APAP from CPAP? Looking at OSCAR it seems at times I have pretty high respiratory rate? Maybe do to REM sleeping? Or is this CSR?

I do notice that I appear to get central apneas when falling alseep or if I wake up and hit the snooze button multiple times, it drive up my nightly average AHI.

Wondering if the posted graphs are considered normal? Recently had a heart ultrasound, and not evidence of heart issues. Thank you!

Are you not feeling well? I think if you do not feel great it may be from something else besides your sleep apnea because your AHI is low. I know most people are more stressed out than normal right now with everything going on in the world.

I used to consistently fall asleep on my back then sometime during the night roll onto my side and wake up on my side.

Lately I have been falling asleep and staying asleep on my back.

I also used to wake up in a deep sleep when my alarm went off and now I am kind of awake before it goes off and I feel I am not in as deep of a sleep?

If my AHI is above about 3 I definitely notice a difference for the first hour or two of the day until the coffee kicks in.

Central apneas during the sleep-wake transition are completely normal. For example, if you pass out and stay asleep for 7 hours straight, your AHI may be 2.0, but if you had a restless night due to insomnia and kept waking up and falling asleep, your AHI could even be like 6.0 or something. Mostly central apneas. This happens to me.

I did a lot of research on it because I was concerned. After waking up from a sleep study, the technician said “you have obstructive AND central sleep apnea.” I spoke with the sleep medicine specialist and he said “you did have some central apneas, but they were happening when falling asleep or waking up. You had central apneas, but you don’t have central sleep apnea. That is not a sign of any disease.”

I used to freak out and obsess but I don’t anymore. Just chill out and try to keep your AVERAGE number below 5. If it actually creeps up above 5 over time then definitely consult with the doc or sleep clinic. An AHI of 2.5 ish is excellent, pretty much exactly what I’m at currently. A gradual movement up or down by a couple points isn’t an issue and can be caused by weight changes, sleep habits etc.
