Mask Blowing Off My Face/Making Loud Air Escape Noises

Postby bigeugene » Tue Mar 11, 2008 9:55 pm

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!

It took me 7 weeks and 3 masks to be able to finally sleep through the night with the CPAP! My victory was with the Mirage quatro as well. I'm at a pressure of 11 at full pressure. I find it too loud when I'm laying on my back, but much better on my side, wiht my mask laying off the edge of a contoured foam neck pillow. Using the ramp button gives me time to really relax before it hits full blast, and I'm now often asleep by then. Don't give up--keep trying different pillows on your side.

Thanks for the tips. I just went and tried to rediagnose the situation. It is not the vents that are causing the noise but the valve in the elbow joint. My wife thinks that's just the way it is, it makes some noise and I have to get used to it. Which sucks b/c I'm a light sleeper. I finally get used to wearing a mask and now I have airflow noise to deal with. Noise was not a problem w/ my nasal mask, but even with a strap my stubborn jaw would open.

I guess you can't win them all, as I am clearly learning through this long process of getting used to CPAP. :)

could be a defective valve? ask your DME to exchange the mask for another of the same type...

good luck!

Hi bigeugene and welcome to the forum!

Do a search here, there are many people with leaks in swivel joints of some of these masks. I believe if you use some tape (plumber's or ? -- please search the posts) you can stop that noise. The Quattro is one of the quietest masks made from what I've been told. (Myself I use a Hans Rudolph Full Face, which is even quieter than the Quattro.)

Thanks so much! You were right, there was a slight leak at the bottom of the mask where the hard plastic and soft seal connect. It just took a little push in and it was fixed!

All is quiet for now.....:)
