Have a CPAP Machine? Beware of GAME OVER

Can't your GP prescribe it? You have a history.

The records from your old sleep doc are somewhere, they usually transfer everything to another practice. You might have to call around and find out who has them, then get the new doc to transfer the records to them. There's even a chance that the records were shared electronically with your GP.

The machine shutting down is nonsense, but it's probably done as a CYA for the company and the doctors.

Side story: I was in the hospital overnight for some surgery a few years ago. Somewhere, someone had checked a box that said "c-pap" or something like that. They kept insisting that they will provide a C-pap machine for me and not to bring my own. Even in the hospital, they kept telling me the C-pap was going to be there. Each time it was brought up, I had to say "I don't use one", but that never unchecked that box. They never did bring one, I think the last time they said it, I was out of surgery and in some pain, so I wasn't in a good mood.... So they got the hint. LOL.
