I have a ResMed P10 - got it at my sleep study. I have played with medium and large sized pillows - the medium seals better but becomes painful more quickly. The large is quite comfortable for 3-4 hours, then starts to make my nose very sore and I wake up.
I also have a Respironics WISP I got at the DME when I took delivery of my machine, and this one was what was submitted to insurance. Started off with the large cushion, but it felt like it was blocking my nostrils, so I went to the extra large. Big improvement, but I have to tighten it down a good bit, and about 4 hours later, you guessed it - it is bothersome enough to wake me.
For the past several nights, I've been going to sleep with the P10 and changing to the WISP in the middle of the night. This is workable, but not ideal, of course. I am apparently less active earlier in the evening, and can keep the P10 mostly well sealed for that time period.
Tossing and turning after that, the WISP is a much better solution; with the P10 during that latter part of the night, my events go way up.
With so many masks out there, at ~$100 each, how does one go about trying enough to find the perfect match? Insurance sure doesn't pay for a selection, that I am aware of.
How did everyone else find their perfect mask?
