RE: transitional/sleep onset apneas after years of PAP
Thanks for all your replies! I truly appreciate it. I’m wondering how worried I should be about my oxygen desats and whether I should get a new sleep doctor. My O2 drops to as low as 70% at night — typically as I’m in the process of falling asleep. My sleep doc responded by saying he’d normally increase my pressure to treat those CSAs but can’t because of aerophagia.
Can that be right? My OSA seems to be pretty well controlled by BiPAP (something like 1.6 AHI on average). My brain just doesn’t tell me to breathe for swathes of the night. He also gave me Ambien a few months ago for these transitional or sleep-onset apneas to make me sleep through them. I seem to have them most every night now though.
My doc has recommended another sleep study to see if BiPAP-ST or ASV might be called for, but doesn’t seem to have any urgency about it. Is this something that can wait for months? Should I be finding a new doctor? I’ve attached some screenshots from my Wellue pulse oximeter of some of my worst nights.
