My new HDM Z1 Auto arrived and I was surprised to find that the MIN pressure setting for auto was 4.0 even though the prescription provided to <Link to Supplier #1 removed by Moderator> was 7.0. I gave it a try anyways. After two miserable nights of feeling like I was a scuba diver trying to draw air out from a regulator on an airtank hitting empty, I had enough. I also saw that the unit really never moved more than .2 up from 4.0 while doing its APAP thing. My AH count, according to their software was also in the mid 40s.
I downloaded the Clinicians Manuals from this site for this new unit (THANK YOU! THANK YOU! THANK YOU!) and set the MIN to my prescription rate of 7.0. Last night was SO MUCH better! I felt refreshed and my AH Count had dropped to 24, almost half of what it was the previous two nights. Not ideal, but way better than before. What I did notice as well as the APAP never deviated from 7.0, even during the one hour where I had the most incidents (yes, it is in APAP vs. CPAP mode).
Two questions: 1) Why do clinicians set the MIN so flipping below your prescription when configuring APAP vs. CPAP? 2) How long does it take for APAPs to "learn" or "react" to what they need to do?
Based on my results last night alone, I feel comfortable taking the HDM Z1 Auto with me on travel, but am curious about my questions above.
