and ps max 15. I messed around with epap and also ps. I was up to min ps of 6. Thinking I was going in the right direction. I also was up to 10 on epap.
I changed back to original settings and now am finally feeling better. When you were on cpap 8-11 that would be on an asv of 8 epap and min ps 3 and max ps can be up to 17 it will only go that high if it needs to. I'm not a doctor but just trying to help. so really need to know original settings, and data from sleepy head if you have it.
Original ASV titrated settings, used for two weeks, waking me up after 2 hrs: Standard ASV - EPAP 8, MinPS 6, MaxPS 14.

I am changing these settings tonight to: Standard ASV - EPAP 8, MinPS 5, MaxPS 10

do you use sleepyhead? You shouldn't need to change your max ps. Is there a reason you want to change that?

I do use sleepyhead. Things seem normal in the waveforms, I just pop awake. I want to change MaxPS because of potential for arousals by wild pressure swings.

wild pressure swings are what ASVs are all about!!!

Indeed!

If you're having trouble falling or staying asleep, work on the minimum settings, but I wouldn't mess with the PS max. The max is there in case you stop breathing and less pressure isn't enough to get your breathing again. It's not just going to crank up the pressure for no reason. So if you don't need high pressure, it won't produce high pressure, and the high max setting won't matter. If you do need high pressure, well, you want that high max setting.

You said EPAP=8. Do you have EPAPmin=EPAPmax? If not, you might be able to lower your EPAPmin slightly, though if you lower it too much and most of your apneas are obstructive and widely separated, it might not be able to react fast enough.

For reference, with my settings (EPAP=5-15, PS=4-19), my EPAP is reliably at 6.0 or lower for 90% of the night. My average PS is 4.1. These numbers tend to creep up if I'm congested, but they're pretty reliable at this stage. Treated AHI=0.0 or 0.1.

The other thing you might look at is your ramp setting. I've got my ramp set to 15 minutes starting at EPAP=4. This sometimes helps me fall asleep to begin with, but it's especially helpful if I wake up and the machine is blowing fairly hard. Pressing ramp settles it back down, and I fall right back to sleep.

And you can keep pressing it as long as you're awake whenever the pressure bothers you.

he'd previously said that he's in asv mode (on the vpap adapt, that's a set epap level, not auto adjusting)
