I have an AirSense 11, been using it for about a month and a half. My AHI went form 55 to under 5 so that's good.
About 3 weeks ago I started getting strong Aerophagia, woke up very bloated with a ton of gas, some pain even. My machine was initially set up to pressure Min 4 - Max 20 so I talked to my Dr, she said she would talk to the machine people to reduce the pressure. After a few days it wasn't reduced, I then had an appointment with her, she said she had asked them to reduce to Max 15 or so and that she called them and that it would happen that day... never happened.
In any case I reduced it to 4.2 - 15.2 (couldn't figure out how to set it to .0). Since then the Aerophagia has greatly improved but it still there, I still wake up with a little bit of gas.
My other concern is a bit hard to explain, it's like chest soreness. I feel like everyday I wake up with this chest or lung soreness, I'm not sure if I'm bloated, it feels a little different. It's not strong pain, it feels like residual soreness. I have also been trying to do exercise and diet so I thought it may be related to that but if I stop the exercise or the diet it doesn't go away.
For example last night I woke up at 3:45 am with a bit of gas and back pain and the chest soreness so I turned off the machine and went to sleep normally and woke up with no aerophagia an no pain.
Maybe I should mention that I have recorded myself sleeping since I got the machine. Without it I would snore like crazy and move around a lot. With it I don't snore, don't move, don't shift, don't make a sound, basically sleep like a baby. I don't feel any different in the morning, I don't feel better or more rested. I feel the same but with the gas and slight pain.
I downloaded OSCAR and started recording but I'm not sure what it all means. Also usually you search something on YouTube like cpap mask fitting or can't breath or whatever and you find something but I didn't find anything about chest pain.
