I recently got a Mirage Quattro (full face) which I actually like. Everything begins fine. However, after my CPAP ramps up to full power, the mask starts hissing (I do not lose the seal, it just makes noise as air escapes through the outflow holes in the mask), the pressure increases significantly and the mask feels like it is going to blow off my face.
My machine is set at 12, which does not seem too high and is on a bedside table pretty close to me. I read on another post that moving the machine further away might help.
Am I wearing the mask too tight? Is my machine too close? Is there a way to allow more air to escape while keeping the pressure high enough? Is 12 too high for the Mirage Quattro to handle (doesn't seem that it should .
My backup mask is the Mirage Swift II nasal pillow mask w/ chinstrap and the pressure is not a problem with that, so I find this all strange.
Thanks for any advice!
