"hi, I use a hybrid mask but find that the nasal pillows pop out under higher pressures. I have experimented with various ways of keeping them in (elastics, etc.) but nothing works completely. Does anyone have this problem and have you found solutions? Also, I would be most interested if anyone knows about someone who customizes masks. Thanks, A. Caspary"
I had the same problem and the only solution was to switch to a full face mask. There is a company in Australia, Acurest Logical® Sleep Mask, that custom fits masks. I don't know much about it though. They are supposed to be working on a U.S. location.
The hybrid had those issues. The liberty (resmed) worked that problem out, but still there's room for improvement. Now why are there Higher pressures, You should only have one pressure.
