But in case I have sell my doctor on why I want the things recommended on this board, I want to make sure I understand why it's recommended. I understand why auto is desired. And I believe data capable is because with all that extra data, I can use something like the sleepyhead software and make my own adjustments if necessary, instead of potentially having to go back to my doctor often just to say "I don't think this is working well for me, I don't know why" as well as better data for the doctor to see how well, or not well, the treatment is working.
I have seen the wiki with the list of preferred machines. The impression I got from my visit previous to the sleep study, was that if I needed a machine I would come back to see the doctor and they would give me a machine. The exact words used were "We will get you back in and set up with something" So I don't know if that means I'll have a rental situation, or where a DME might come into play, if she meant I'd be given a script to fill with a DME or whatever. Mysteries for the future to solve.
