Hi.
CPAP user here.
I use a mask. They started me with the nose mask, but that didn’t work. I breathe through my nose and my mouth simulataneously all the time, and so had my mouth open while the CPAP was blowing air through my nose - sounded funny, felt really strange, and didn’t help.
A regular full face mask works much better for me. I have to tighten the straps really tight, though, to keep it from leaking and blowing air in my eyes or making fart noises all night.
I’ve found it works best to run the hose over the head of the bed (if you lie on your back then the hose would run over your forehead, then behind the bed, then down to the floor where the CPAP is.) If I don’t run it over the head of the bed, I end up with the hose wrapped around my neck - not comfortable, and a strangling hazard. Run over the head of the bed that way also allows me to toss and turn without needing much slack in the hose.
The fracking masks are built ass backwards, of course. There is a grid of small holes that lets out air when you exhale, and of course it is right where the hose runs when you lie on your back with the hose going over the head of the bed. When the hose is over the holes, I get a hissing noise. Since I sleep on my side, the hose is mostly canted the side a bit, so I don’t have a lot of trouble with that.
The hose shouldn’t have any dips in it - it should run as straight as possible from the head of the bed back down to the machine. This will let the condensed water run back into the machine instead of running into your face or collecting in a low spot and making gurgling noises.
Park the CPAP on an old pillow UNDER your bed. The machines vibrate a bit, and the pillow will damp the vibration - if I don’t do that, the whole bedroom hums. Putting it under the bed will help muffle the sound of the air intake.
My CPAP dynamically adjusts the pressure, so when I go to sleep it is very quiet but gets louder during the night. When things are really bad, it makes a “chuffing” noise in time with my breathing that drives my wife nuts and sometimes wakes me up. Being under the bed muffles the intake noise a lot. If it doesn’t help enough, a thick down comforter wadded up over the CPAP can help reduce the intake noise even more.
I wash my mask every morning as part of my daily routine, just after brushing my teeth and before cleaning my glasses. I keep a bottle of dish soap under the sink. Squirt a few drops on the seal and the forehead pads, scrub with fingers, rinse under HOT water, shake out over the tub, let dry all day. Once a month I disassemble the mask and scrub all the hard reach cracks and crannies using a tooth brush and Q-Tips.
The straps on the mask have velcro closures. I hate them. They wear out, then the mask comes undone in the night. Right now I’ve got the straps adjusted well and duct-taped so they don’t come unstuck. I’ll sew them down the next time I wash the straps. The damn velcro also likes to stick the the blankets - you roll over and “riiippp!” the mask falls off.
Adjusting the mask is pain if you have an auto CPAP like mine. If you adjust it so that it is comfortable and doesn’t leak before you go to sleep, you will likely wake up with it leaking all over hte place and blowing in your eyes and making fart noises. To adjust: Put the mask on and tighten until it feels like it ought to have a good seal. Attach the hose and turn on the machine. Take a deep breath and huff it all out in one big, powerful burst. This will run the pressure up to something like what the machine uses during the night. If it leaks, readjust and retry. Keep adjusting and retrying until huffing no longer causes leaks.
I run the humidifier on the lowest setting. That keeps my nose from drying out, but minimzes the amount of condensation. I do have to have the humidifier, though. Without it, my nose dries out and I don’t just get boogers - I get BLOODY boogers and sneeze blood in the morning.
Honest to christ I don’t know how the manufacturer’s expect anyone to deal with the machines without all of the above having been explained. Mine drove me nuts for months before I got it all figured out. Sleeping with the mask wasn’t problem. Sleeping with a mask that liked to flop around, get loose, leak, and make noise was a major pain.
