So I got a new Airsense Auto and oxygen concentrator had a good first 6 days of sleep. AHI was about .6 for those days with leaks almost nill using a headband over my mouth/cheeks.
Then last night the O2 concentrator started alarming (very loudly) at about 3am. I ripped my mask and headband off and went to see what was making that noise. (I thought the house was burning down.) So I ended up turning of the O2 and and losing the headband somewhere in my panic to get the alarm silenced.
I went back to sleep and cruised for an hour or so before everything went to heck. This is the report from that section in time. AHI for the whole night (including an afternoon nap was 16, but the AHI graph hit 90 during the worst of this segment!
I had some leaks without the headband, but they don't directly correspond to the events recorded. I woke up with a headache and mild dry mouth.
Is This Cheyne-Stokes? My sleep study said I didn't have any evidence of this.
Leak, but problems preceded it.
I don't know what to make of these patterns. Any advice?
