Resmed Air Cushion Design
#1
I've been using a Resmed Quattro FX for about five months. I had a brick for most of that time, so I had no data about leaks. I got an S9 autoset about two weeks ago, and found that my leak numbers were terrible, and I've been working to get them down since then, with mixed success. I use the "mask fit" feature and always start out the night with good numbers, but as I fall asleep, things start to go south, leak-wise.

As best I can tell, the problems I have are on the sides of the mask, not the top or bottom. I added a strap below my chin, running through the two bottom straps to prevent the mask from riding up, which has worked well. Now I have started using strips of bandage tape on the sides of the mask. I'm using 1" tape and folding it in half, so that one half adheres to the cushion and the other half to my skin. This way, if the mask lifts up, instead of being open, the air will be trapped by the tape. So far it's working, but I've only used it twice.

Between the extra strap and the tape, putting on the mask is getting to be quite a production. The secret of getting a good seal with this mask is supposed to be not over-tightening, so the double walled cushion can fully inflate, but it seems like the shape of my face changes too much when I sleep, and the cushion can't adjust.

So I'm looking for any tips or suggestions which might help. I haven't tried mask liners. Money is a bit tight, and I'm hoping to find a more cost effective solution. The tape might be it, but it's a bit uncomfortable, and I'm having to tighten the straps too much to get it to work.

I've been training myself to nose breathe, and today I ordered an Airfit N10, but even if that works out I still want to make a full face mask work, for times when I'm congested.

You can make your own mask liner out of an old t-shirt, or even a new t-shirt, or even t-shirt sort of material from the fabric store.

Just trace around the mask cushion on the material leaving some border inside and out, then cut it out. Cut out the center so you have a nice place for your nose to go.

I think you'll like the N10 better than the ffm once you get used to it.

I just noticed this statement: "I've been using a Resmed Quattro FX for about five months."

Reviewing the schedule for replacements I received from Providence Home Services I noted the mask should be replaced every 6 months and the cushion should be replaced at least every month. This could be part of the problem. I Completely Understand about tight finances - is there any way you could get supplies through the insurance or a program such as this? (I hope the moderators are OK with my putting this info here; if not, please let me know.) I searched on Resmed assistance and found this info on the first page of the results.

=====================
“Supply has always been our challenge, but thanks to ResMed, we will now be in a position to increase the reach of our program,” said Nasca. Physicians and social workers can refer patients to apply for assistance at http://www.sleepapnea.org where forms are provided. Inquiries may be sent to CAP@sleepapnea.org.

Another support program of the ASAA is the A.W.A.K.E. network. A.W.A.K.E. stands for Alert, Well, And Keeping Energetic. Its education and support groups are available in nearly every state, helping people face to face and free of charge. A.W.A.K.E. gives people with sleep apnea the educational tools to help manage their own diagnosis successfully."
=========================

I am assuming you are washing the FFM daily and letting it air dry; which helps keep you breathing clean air and helps the mask last longer.

Links to non-profit sites are fine. It's the commercial website links we have to limit.

You might want to try boiling your mask cushion with baking soda, to make the silicone more flexible to reduce leaks, and to remove skin oils. I put about 1 teaspoon of baking soda in a quart-sized container of boiling water. (You will need a larger container for the Quattro FX.) Then, I put my mask cushion in until the water cools off. It will turn out slimy from skin oils, and will need to be cleaned. I'm able to get about 9 months out of a mask cushion.

Do you mean it will be slimy after you boil it and then you clean it as usual in warm soapy water?

That's good info that I'll be able to use, thanks for the tip.
