Losing mask seal around 1:00 a.m.

Janknitz wrote:Take a look at my mask fitting suggestions in "Taming the Mirage Quattro". I have the forehead piece dialed all the way out so that the mask is really tilted away from my nose. Then I make sure that there's plenty of air filling that nose piece before I adjust the mask. That helps reduce the pressure against my nose, while making a good seal.

I read your fitting suggestions a few weeks ago. Thanks for putting them on line! They're the reason I decided to give the Quattro another try, and following them makes the mask work really well and be very comfortable for me (i.e., I can forget it's even there) until the pressure gets up around 12 (I think). I think that's when it's starting to leak on me. When I tested the mask at 14, last night, I could *not* get it to stay sealed and had to tighten both sets of velcro straps a lot to get the air not to blow out either at my chin or around my eyes. I did have the nose piece dialed all the way out because dialing it in just made things worse around my eyes. However, I'll read your instructions again (I printed them out so I can take them with me) and try to get the mask to seal at max pressure again.

Sue - I dial mine all the way out AND I have a tisues paper folded tightly under it to give it some extra tilt otherwise it never meets my chin.

Just read about the Pad a Cheek leak strap. It might also help. I'm ordering one today as I get leaks from sleeping on my side.

Jank, Can you post a photo of your liner?

I'm working on it, Doric. I took the photos but I need to find the card reader that works with the camera--it's not a standard one, and who knows where the kids put it this time--should have used my phone!???

It's very interesting looking at my data. I'm having a good amount of leaking with the Quattro which is driving up the pressure, but interestingly, my AHI is the lowest ever 0.0 to 0.2! The leaks are not so large that the machine can't handle them--I've had only the slightest bit of black on my leak line. I think the fact that the machine has to compensate for the leaks is actually helping my AHI.

This is making me wonder if I might do better with just a tiny bit more pressure, I'm also feeling really rested in the morning.
