I got the Dreamwear which seems to fit great and is very comfortable, and excitedly went to bed with it. There were no leaks that I could find and I'm very sensitive to the feeling or sound of air escaping anywhere, so I'm pretty confident. The only issue with mask fit is that the headgear strap tends to ride up and make the mask loose, but I never got to worry about that much....
As I tried to go to sleep, I noticed much more noise both from the mask and the machine, then I did have trouble keeping it sealed as I tossed and turned but it felt very different. This only got worse and my chest started feeling uncomfortable. I looked at the machine and it was up to 16! I've never been that high. I checked everything, humidifier sealed, tubing secure, etc. and found no problems so I restarted the machine. It went from 4.. To 6... And then kept climbing for no apparent reason. I never fell asleep with it (husband agrees and my FitBit does too) and kept tweaking things (setting for nasal vs. FFM on machine) and restarting the machine. Nope, every time, the pressure just kept going up. This didn't happen with the Wisp I tried recently (hurt my nasal bridge and went back) and nothing has changed. When I looked at the sleep report I found AHI 4-5 TIMES my usual when sleeping (same AHI even during periods where I only had the machine running for 20 minutes to try to fix things) ... But I was awake and definitely breathing continuously!! Leak reported was zero and my DME said the machine wasn't reporting any issues so it must be leaking somewhere to cause this issue. ??? I asked the doctor to lower the upper pressure limit but played phone tag where he advised me to have the machine checked instead I know I can do this but the DME is strongly advising me I'd better not for legal reasons.
The first night of struggle I actually removed the mask and slept without it, it was after 1am and I felt awful. Since I knew the new mask fit well and was pretty quiet, I was confident I would use it all night so didn't have my old mask within reach for switching.
Last night I switched to my Amara after 10:30pm and a repeat of the issue when trying the Dreamwear, and things were fine. Usual AHI and pressure reported. No escalating out of control!
What could cause this odd overdetection and then higher and higher pressure? I don't think I've ever hit 9 before this.
