Surprise....Apnea...
I went in for a totally routine doctor visit and casually mentioned that I snore a bit. I honestly expected the conversation to end with “lose a few pounds and sleep on your side, buddy.” Instead, my doctor suggested an at-home sleep study “just to check.”
Well… shit.
The home study came back with:
- AHI 77.6
- oxygen down to 70%
- about 74% of events classified as central/mixed apnea instead of straightforward obstructive apnea
Meanwhile, I feel… basically fine?
No excessive daytime sleepiness. Blood pressure is normal to low. Good exercise tolerance. I hike/camp regularly at altitude in Colorado and generally feel functional and healthy. Honestly the biggest stress so far has been navigating the medical admin circus itself.
One wrinkle that may matter: I live at about 7,800 ft elevation and regularly sleep/camp around 9–10k ft. From what I’m reading, altitude can apparently contribute to central apnea / periodic breathing in some people.
At this point I’m trying to push for a proper in-lab split-night polysomnography + titration study instead of just blindly getting thrown onto auto-CPAP. My understanding is:
- CPAP/APAP is usually for classic obstructive apnea
- ASV may be more appropriate if the central apnea component is truly dominant
- home studies are not always great at accurately classifying central vs obstructive events
Curious if anybody here has had:
- severe home-study results that changed significantly on full PSG
- altitude-related central apnea
- experience with ASV vs CPAP
- or generally similar “you should feel terrible but somehow don’t” situations
Also curious whether people think an altitude lab is worth pursuing in my case versus a normal Denver-area lab.
Trying to approach this rationally without either ignoring it or turning into a full-time sleep apnea hypochondriac. Appreciate any thoughts from people who’ve been down this road.
