I use a ResMed S9 VPAP Adapt for central & obstructive apnea.
The machines constantly break and I'm concerned that the newest one is breathing its last, as well.
My apnea was well-controlled and stable. The AHI and AI were zero, night after night. All was going very well and and then one night in December - boom -- the AHI and AI went straight up and stayed up for no reason I could think of. I had not changed drugs, gained weight or anything else that might account for it so I had it replaced .
The replacement came on Dec 11 and the real-time results LCD was a horrific mess. The screen was marred, had two lines that shouldn't have been on it and the numbers were scrunched and very hard to read. The numbers remained terrible. My sleep specialist and a therapist in his office examined it on January 20 and agreed it was dead the day it arrived.
A replacement, model 36037, was delivered January 21 of this year and the real-time results LCD display format does not match the display shown in the manual. It's not nearly as bad but it still doesn't match the manual and the results are just as bad.
If I post some links, would someone please take a peak at the pictures and a video I posted on the web. If that's not allowed, I'd be happy to email the links to you. Thanks.
