Machine questions...

[Whatever Everybody]

Hi,  I've been using a cpap since 2013.  My first machine was a DeVilibiss Intellipap Auto-set that was manufactured in 2013.  It worked great until last week when I got some water in the electronics and fried them.  The next day I was loaned a ResMed Airsense 10 that was manufactured in 2018.

I saw that, after the first night of using the ResMed, my AHI was 1.8/hour.  The next night was 1.4 and last night was 1.0.  These numbers are WAY, way lower than when using my old DeVilibiss (average of ~15/hour regularly).  I was totally shocked by the difference.

So, my questions are these:

1. Has the technology/algorithms used in these machines improved dramatically from 2013 to 2018?
2. If not, could the ResMed machine need some sort of professional calibration?  It was loaned to me by another user who hasn't used the machine in months and months.
3. Or, lastly, do some machines just work better for some people than others?  IE: do folks sometimes have to try out a few different machines until they find that one that works best for them?

Any info would be appreciated.

Thanks.

I found exactly the same thing.
I went from a CPAP Brick with an Rx of 19 cmw but only producing an "OK" 17, to a DV54 Auto CPAP and about 2 years ago to a ResMed VAuto.
I felt the DV54 was very aggressive on defining events and as such provided what was presumed equal but in actuality a higher number of events. Without knowing this it drove me crazy, I couldn't manage my numbers effectively with the DV54 and that led to my push to get a ResMed VAuto.

You have IMHO the best of the AutoCPAPs for a number of reasons. Specifically, you want either the ResMed AirSense 10 AutoSet or the AutoSet for her.
