I'm going to try these settings again tonight.

I agree. You want to be careful that you don't induce aerophagia.

RE: Managing flow limitations
Setting my pressure at Min=7.6, Max=9.2, and EPR=3 does seem to have helped quite a bit with the flow limitations.  I'm now mostly seeing CAs with a few OAs or Hypopneas.  

I tried increasing my Min pressure a little more to get ahead of the OAs and ran into aerophagia so I backed that off.  I guess I'll try a full week or two at these settings to see if I have enough quality sleep to start feeling better.

That looks really good! But remember that 1 night doesn't make a trend. Stick with these settings for awhile and see how you feel.

If CA's go up, you can always lower EPR.

RE: Managing flow limitations
I've been waking up around 5:20AM most days so I bought blackout curtains to see if it was sunrise.  Still waking up earlier than desired and not feeling well rested.

Some nights I have no significant flow limitations.  Other nights I'm still having clustered flow limits with some RERAs.  Is there any good way to figure out what's causing this other than getting a video camera to make sure it's not positional?


   



And here's a zoom into right before I woke up in the middle of the night.  This happens around 1/2 of the time.  Not seeing anything obvious here other than a long (false?) CA where I took a real deep breath and then a few minutes later had a RERA.

RE: Managing flow limitations
It appears that your flow limitation is driving up your pressure. You might be sensitive to the pressure change. Your profile lists a 7-8 range, but the OSCAR report shows a 7-9. Have you considered setting the pressure to a static 8 cm, still keeping an EPR of 3, and seeing if you feel any better?

RE: Managing flow limitations
Ah, I didn't update my profile pressure text after all the advice earlier in this thread.

I used to be at a static pressure but around 7-7.6 and that left me with a lot of flow limitations.  I can try moving it higher at a static value to see if that helps or if I get too much aerophagia.

RE: Managing flow limitations
I would try to figure out if you find fixed pressure or a pressure range seems to give you better results then I would try slowly increasing pressure to see if it helps. If no obvious improvement come back to lower pressure.
