My doctor reassessed and advised me to use the Resmed airsense 10 APAP with a new mask. I had already changed two DMEs earlier. When I contacted a new supplier, they wanted my doctor to send them his order. The process went through some botched mailing and finally they said they are ready with the machine for me, though it seemed the person at the end of the phone line was not quite sure exactly which machine they would be giving me. She assured me that whichever it happened to be it would work just as good and it made no difference to me. It would cost me the same anyway. I was not happy with what they wanted to give me and in the meantime it was getting close to when I had to see my doctor about how the machine was helping me. So I am back to square one. I am now thinking Landauer Medstar. What do you people think about Medstar? Has anyone had a good experience with this DME?
