I started cpap 5 years ago. Couldn't sleep with the screaming monkey jumping up and down on my face. I quit after the worst 4 months of sleep. Got 5 years older, apnea apparently got worst or less able to tolerate it, so I tried again. A Dreamstation (Apap) and a Dreamwear nasal mask. Now the fun began.
Blowing in my nose is a good thing, because I have nighttime stuffiness, but the pressure keeps the nasal passages open.
I recommend the mask because it's so unobtrusive.
Now the bad things.
Air goes in my nose and out my mouth.
If I hold my mouth closed it burbles through my lips
If I tape my lips shut, it blows up my checks
and then blows off the lip bandage.
All of which either keep me from falling asleep or wake me up multiple times.
So all those ad pictures of the happy nasal mask wearers...I don't believe them.
The typical solutions of tape and chin straps don't work. Tape blows off and fabric straps, still allow the mouth to open. Full face masks don't work for me, nor an oral cpap mask.
I went to a dentist and I asked him to make a form fitting oral appliance, which is molded to my teeth and locks my jaws closed. You can see it in the center of the picture.
I found 3 X 4 inch waterproof bandages at Rite Aid 6 for $2.99. This keeps air from coming through my lips.
I made a Silence of the Lambs strap from a steel plate that covers my lips and cheeks. Steel, because poofing cheeks require a lot of rigidity to keep them from poofing. The steel is covered by 2 inch duct tape and has a polyethylene foam liner around the lip area. A Velcro strap around the back of my neck holds it in place. This also keeps the bandage from blowing off.
I ain't pretty at night, and will need a suitcase to carry all my parts, but at least I'm sleeping >6hrs a night, AHI about 3.5, 90% Pressure 12.5.
I believe the min Apap setting should be set .5 to 1 cm below the 90% pressure, to limit the number of events it takes to step up the pressure, to get to the 90% pressure.
Your thoughts?
