I'm glad to hear your husband is getting less aerophagia on the BiPAP. That's also been true for me. I'm running my PR S1 BiPAP Auto in straight BiPAP mode though with fixed IPAP=8 and EPAP=6 though and have set the ramp to 30 minutes with starting pressures of IPAP=7 and EPA=5.
One thing you might have your husband experiment with if he's still having occasional trouble with the aerophagia is Bi-Flex versus the Rise Time setting. (I think both options are still there in Bi-Auto mode, which is what it sounds like your husband is using.) I found that I was much more comfortable with Bi-Flex turned OFF and with Rise Time set to 3. My problem was that I could feel the slight increase in pressure back up to full EPAP during the second part of my exhale on every single breath and it really tickled the back of my throat in a most uncomfortable way. And that sometimes lead to my unintentionally swallowing air.
So check to see whether your husband needs the Bi-Flex turned on. Since his EPAP is already down at 6, he may not need any additional pressure relief at the start of his exhale and turning Bi-Flex off might help the residual aerophagia issues.
I'd report the morning headaches and their association with the days where the IPAP is over 10 to the sleep doctor's office if I were you. Sounds like a strange correlation. And it might be worth limiting the top IPAP for a trial period to see (1) if the morning headaches disappear and (2) there's no increase in AHI overall.
Thanks RobySue
I will let him know. For right now, you were right, he is in Auto mode. The doctor wanted him to auto-titrate for a bit, then send the info in. So we won't be changing anything on the machine just yet. We (I mean "he") has an appointment next month, so we will see how it goes.
