switched to ASV - Feeling better but still struggling with aerophagia
Hey everyone,
i used to be on APAP/CPAP but switched to Vauto. Recently, i wasn't really happy with the therapy. too many arousals.
So, i adjusted my settings and switched my machines to ASV mode. Honestly, it feels better now.
The settings were kinda tricky, but i think i got them right.
the only issue i still have is aerophagia. any advice?
RE: switched to ASV - Feeling better but still struggling with aerophagia
Your pressures are pretty low with ASV and the only place you have room for lowering pressure is in the EPAP max of 10. Some people find aerophagia is reduced or eliminated by raising the head of the bed. This is not a wedge pillow but using 3-inch blocks under the bed frame to build up an angle of 3-6 inches. https://www.amazon.com/s?k=bed+raising+b...%2C127&ref

I recommend lowering EPAP max until you see an unacceptable level of UA or H events occur. EPAP is used to stent the airway to prevent obstruction, while PS is used for ventilation and to help you trigger breaths if needed. I like your PS range of 2-7, so really the only place you have to cut is in the EPAP.

I thought so.
I took both machines apart and compared them chip by chip.
Literally, the only difference between the two is the outer casing.
I don’t use AirBreak. I completely removed its firmware from my machine and replaced it with the PaceWave (ASV) firmware.
But can you explain why it might not respond as expected, even though the hardware is exactly the same in both machines and the only difference is the firmware?

I’ll try lowering it by one and share my results with you in a few days.
