Cloth Mask Liner?

Post by monica4patience » Sun Dec 19, 2010 6:45 am

I started using a cloth mask liner (home-made from 100% cotton) on Friday. It was a short night for me after DH's office party. I used it again last night for a longer sleep. The mask was comfortable, but I couldn't really tell if it was leaking or not. I didn't get that rush of cold air. Maybe because it was filtered a bit by the cloth. But it also seemed that the air pressure was not as intense. DH said it was much quieter.

My numbers were quite good (well except VS on Friday). But I'm just not sure how accurate they are. Can the cloth mask liner interfere with how the machine is working? How it reads the apnea episodes? I guess I'm just not trusting that these numbers are a true reflection of what happened.

Leak graph looks really good, no trouble there, you probably aren't noticing the pressure anymore :D . Can't see all numbers on right side, but looks like AHI is 1 something, also really good. Snore and RERA high, you might try a .5 increase of pressure, maybe an increase of flex if it is more comfortable. JMO, everything really looks good, :D cheers kathy
Any landing you walk away from is a good one; if you don't break your airplane it's excellent.

I'd trust the numbers -- insofar as data numbers from our machines can be trusted at all. Data from our machines isn't as much "a true reflection of what happened" as the data from a sleep study PSG would be. Best to regard our machine data as useful for trending purposes mainly. But I digress! I suppose you're talking about comparing numbers you got when using the cloth liner you made (the two graphs you posted) to numbers you've previously gotten without the cloth liner.

I assume the liner was cut out in the middle in the shape of the mask opening, and the cloth was cut to line the area where the silicone of the mask cushion touches your skin. I'd say your CPAP sensed the airflow just as well as it did without the liner. Sounds like what you made worked fine.

Regarding the increase of events your data shows in the last hours before morning... apneas are most apt to happen for most people when the person is in REM (rapid eye movement -- "dreaming") sleep. REM cycles usually get increasingly longer as the night goes on.

With that in mind, I'd probably try a few nights using a little more pressure, as Kathy (mayondair) suggested. If it were me, I'd raise the pressure (currently set at 8 ) up to 9 or 10. There's nothing wrong with a more conservative change like .5 cm. I just prefer to make my changes in whole cm's -- either direction -- when I'm tweaking my own therapy.

Even if you don't make any pressure change, you're lookin' good, Monica. What a bee-yoo-tee-ful low leak line! Lucky you! :D
