Mom has RA, Alz & Central Sleep Apnea. Machine's alarm constantly sounding & she can't adjust mask. The RA has left her hands with extremely poor dexterity. The Alz overshadows her problem solving sense. The pressure settings on her Bi-Pap are on the high side so she doesn't tolerate nose-only masks. We've gone through a plethora of masks. I've given up on the folks that fit her for masks. Of course the anatomy of her face poses its own problems. So, after trying 3, I finally found the best fitting mask for her. At first the straps that hold it on posed a problem. She'd get everything tangled trying to get them around her head. So, I found a "cap" that fits on her head like a swimming cap...only it's breathable material with straps that connect to the mask...She can manage getting it on herself. Lack of dexterity and hand/eye coordination deficits makes adjusting the mask independently almost impossible. So, I have the best fitting mask I can find, found the best headgear for the mask, I can get her all snugly into her mask...Then she lays down and for the ensuing hours the machine's alarm is constantly going off because of air leakage due to a change in position. She can't sleep like a mummy, she can't figure out how or what changes/adjustments to make. I even have meet with an occupational therapist to see if they could come up with something. They looked at me like I was an alien. Don't they craft adaptive equipment? If only I could modify a snorkle mask. Those at least seem to seal pretty well & they're a heck of a lot easier to work with. Sorry for the list of what I've tried. I thought I'd see if anyone has any tricks I haven't thought of?!?!
