Sounds like my new sleep dr. and one I had in the past.
I just saw this post; I realize I’m two years late. Hopefully you or someone will see it and find it useful.
I don’t care how bright someone is, or how many diplomas hang on his/her wall, there is no excuse for the way he talked to you.
If he can’t take a few minutes to answer your questions/ concerns maybe he’s better suited to research where he doesn’t have to deal with human beings who have feelings.
I understand about the insurance and sympathize with you. Can you find a sleep doctor or facility who will work with you financially? Will MAYO?
Most of the progress I made with my Cpap was on my own, reading patient forums (cpaptalk.com is a good one, plus this one) and Dr. Google. I just let the technician do what he was ordered to do, then I took it from there.
I know some people will disagree, but it really is how I did it. Not telling anyone not to see a doctor, just relating my own experience FWIW.
BTW, I have read that higher Cpap pressures can encourage centrals in some people.
Best of luck to us all🙏
