Ok, so to achieve an EPAP min of 9 (and assuming that if I *do* use EPR, it's set to 2), my options are:

a) set CPAP to 9 and turn off epr
b) set CPAP to 11 and turn on epr 2
c) set APAP min to 11 turn on epr 2

Do I have that right?

c) set APAP min to 11 APAP max to 11 turn on epr 2
d) set APAP min to 9 APAP max to 9 turn epr off


A minor change, and option c or d would be slightly preferred because they would enable the "Flow Limit" chart

I'm not positive, but I think Resmed Autoset will record flow limitation in CPAP mode.  Philips definitely does not do FL flags in CPAP mode.

The S9 Autoset DOES record flow limits in CPAP.

Then it seems reasonably safe to assume the S10 does, too.

This is the option I'll likely go with tonight. Thanks

So last night I set it to CPAP mode at a pressure of 9 with EPR off @bonjour - it *did* flow limit). My AHI was 1.31 for a total time of 7:34. At first glance, those numbers looks good. The interesting thing is that the 7:34 was broken up into 7 small sessions, with the longest two being 1:54 and 2:04; I was up and down quite a bit during the night. This is somewhat consistent with the previous night where my APAP range was set to 10-16 with EPR off; my AHI was 0.87 for a total sleep time of 5:34 broken into 7 shorter sessions.


This is in contrast with two nights ago where APAP was set to 10-16 with EPR of 2. My AHI was up at 2.56, but I had only 4 sessions that averaged longer.

So, when EPR is off and EPAP stays constant at 9 or 10, my AHI may be lower, but I seem to get up and down all night.

However, with EPR on, my AHI may be slightly higher, but I get up and down less, and each of my sleep sessions last longer.

The question is: why? Why do I get up more when my EPAP is fixed at 9? Is it due to comfort? If so, then EPAP pressure must be disturbing me more than I realize - because I don't consciously notice much discomfort when EPR is off.

I'm not sure which scenario is better. If I had to choose, I'd be inclined towards the higher AHI with less getting up and down at night. Waking up to pee has been a major complaint throughout most of my life - so the less I do that, the better I seem to feel.

The next frontier is to try and get my AHI down *with* longer sleep sessions. Any feedback is appreciated.

Go for comfort and less sleep disruption. The rest will take care of itself in time.

Less getting up to pee is better sleep.

Sleep-well

Thanks, I agree. When you get a minute, as a favor, would you have a peek at the above data and see if it takes you to the same conclusion?
