RE: Is this the best I can do?
This is just a couple of nights of Oscar readouts, but I thought I'd post. With just C-Flex on at 2, I was still experiencing some aerophagia. So I thought I'd fool around with the flex settings. On Saturday I used A-Flex at 3 and min. pressure of 12. I got through the night without swallowing air....then Sunday night I kept A-Flex at 3 and raised min pressure to 13. It seemed to go okay with no aerophagia.
I was wondering about the A-Flex set to 3. Is that an okay setting? The Oscar results seem better to me, but I would appreciate input. Could I do better?
Also, I have Barrett's Esophagus which is caused by reflux. I read a study that showed that CPAP aerophagia can contribute to further reflux. I need to be really cautious.

I'm of the mindset that if it's working for you with good AHI results, then it should be fine. AHI and comfort both count. I've got GERD and left side sleeping tends to be better to cope when that's been stirred up. Your own acid reflux issue probably acts similar. When that's in play, do what you must to maximize the comfort level, even if it comes to getting a higher AHI for a while.

Your median tidal volume is low for your height. That's probably mean that you are dealing with chronic flow limitations. Do you see a lot of flat topped inhalation in your flow rate graph? Something like this :
If that's the case, switching to a bilevel should help you. It should help your aerophagia as well.

My flow rate charts don't look like what you posted, but they look pretty irregular. Attached are random samples from one day.
Yes that's exactly what a flow limitation looks like. Some people are chronic sufferers like I was and it seems like you are. If you set the scale to -50/50, you'll see that your flow rate it's similar to the picture I uploaded (the top of the curve is flattened). A bilevel would probably be the better machine for you.
You seems to have some central apneas though. A bilevel could help with that by decreasing the EPAP but it could also make it worse. I think it should be your next step.
