I tried to ask for a Resmed Aircurve 10, but the doctor strongly recommended the Löwenstein Prisma 25S instead, so we had to choose that.
On the old machine he had a steady 7-10 AHI with the following settings:
Min EPAP 10.0 Max IPAP 22.0 PS 3.0-6.0 with Bi-Flex 3
EPAP is decreased to 6 by the doctor last year, but since it caused a lot more apneas, we went back to EPAP of 10.
With the new machine he prescibed the following settings: min and max EEPAP is 6 on trilevel with PDIFF 2-8.
This machine has a little unusual terms, but according to this video (https://www.youtube.com/watch?v=OfuJekqlNL8)
roughly EEPAP is EPAP and PDIFF is PS + Bi-Flex in normal Bi-Level terms. If I'm correct.
Interestingly, it seems like if min and max EEPAP is the same, then PDIFF will not change from the minimum level either. It stays on fixed level of pressures.
The best setting so far is EEPAP between 7-8 and PDIFF 2-5 and the doctor's fixed setting.
This is approaching the old machine's 7-10 AHI if I'm not count central hypopneas (I don't even know why prismaTS calculates it separately)
So far, any attempts to increase EEPAP or PS lead to higher AHIs, more unstable breathing, mouthbreathing, and I think some burping (aerophagia?).
Now I'm not sure how should I compare the results with the old machine.
Should I just look at AHI without CH and accept that he's fine with the lower pressure levels and the new machine is just more strict about hypopneas?
Or is there a room for improvement?
In this case, can you please make some advice what adjustments would be worth to try?
If I just stand by him while he is sleeping, I think his breathing is worse than with the old machine.
If I ask him he always says he slept fine.
He has several other medical conditions (high BMI, CKD, strokes, diabetes, neuropathia, had colon cancer)
I'm attaching some screenshots from the old machine's OSCAR report and the new machines PrismaTS reports.
