This VPAP Adapt is beyond me, sorry to say.

I don't quite understand your math here...
I gather you have
EPAP 7.4
min PS 1
max PS 6

That would mean your IPAP can range
from 7.4+1 = 8.4
to
7.4+6 = 13.4

which is right on what you said Sleepyhead showed.
Does this make sense to you?

OK, this could be where I'm confused. I thought the net PS being 5 would mean it could only go from EPAP (7.4) plus 5, giving a max IPAP of 12.4. So your method takes the min ps of 1 and adds to the EPAP to set the min IPAP, and takes the max ps of 6, adds it to the EPAP to give the max IPAP of 13.4. That would make the difference. I thought we were only dealing with the net ps, not the ranges of ps.

Everybody is different in their needs.
Everybody is different in what their doctor orders.
Everybody is different in what works.

Also, you have to have a machine model that provides auto EPAP capability.

So mainly just more flexibility? I mean it seems to be working pretty darn good for me so I'll just leave it alone. Thanks jcarerra.

I think it's that we have the same machine, but you have yours set to asv auto mode (which allows a range of EPAP), while I have mine set to asv mode (which allows only one EPAP setting).

So I'm wondering why our doctors set us on different modes. Maybe there's an advantage to one way or the other? Maybe I'd like a range of EPAP. Is that the only difference between the 2 modes?

I don't know how it would feel if my EPAP varied all the time. But then the IPAP does, so maybe that would be fine. And the fact that I have trouble breathing out against pressure might make that range more comfortable for me.

By the way, my AHI was .1 last night, with 10 hours of sleep! No air swallowing, great dreams. These adjustments have made all the difference.

Side comment...
remember that long sleep time LOWERS your AHI, which is an average
(dividing by hours and 'hours' is bigger, lowering the answer),
given the same number of A's and H's.

I used to have clusters of say 30 OAs.
If I woke up right at the end, I could have an AHI of, say, 10.
If I slept the rest of the night, the AHI would be, say, 3.
10 vs 3 -- big difference.

Yet same number of AH's happened. The terrible cluster still existed/happened, but AHI of 3 could be called 'acceptable,' but the situation was not acceptable at all.

Yes, that must be right.

I had only one hypopnea the whole night, but on the event log it said it lasted for 54. I assume that's 54 seconds, almost a minute. That seems like a long time to not breathe.

Unsure

I had some in the 50's too before finding that putting a balled up sock inside a sock tied onto a belt to hold it in center of back--preventing supine sleeping--eliminated the clusters.

Note that the length of the apnea will not change the AHI number, only the quantity of them.
