That's another good point 1day. I'm concerned, too, if my insurance even covers this machine. But then, it's medically necessary, right? I mean, they say this can lead to heart disease. I really feel for you with your husband. There were a couple of times I woke up unable to breathe and I just began rather intensely patting my husband. He woke up and just said "Breathe, Breathe." It's a serious condition. I sure hope insurance covers this - for you and for me.
