My girlfriend has been diagnosed with sleep apnea and given a CPAP machine. The problem we’ve run into is that she takes it off in her sleep. Every night we put it on her and every morning, it’s off and she has no recollection of removing it. I can confirm that I’ve seen her do it in her sleep. I tried staying up to put it back on her but I can’t stay up every night to put it back. If she gets up to go to the bathroom or whatever, she always puts it back but inevitably every morning it’s off when she wakes up. Has anyone run into this problem and if so how did you fix it?
