I have been having issues with severe aerophagia for just under a year now. I've also not been feeling very rested even after sleeping on average 7.5 hours a night.
I was using an M Series CPAP Pro at a pressure of 10cm, and supplemental oxygen at 2.5lpm. My AHI is routinely under 2 at an average of 1.2. I visited my sleep doctor and went over what I have been experiencing. In looking at my sleep report from a year ago with the doctor we saw that when CPAP was implemented all my event turned to centrals.
To deal with the aerophagia we determined that I need a lower exhale pressure. He also suggested that I should have an auto to record NR and FL since my machine would not record them. He suspects that I am still having centrals.
So last night was the first night on my new machine "M Series Auto BiPAP". I have included the nightly report below.
He prescribed: Min EPAP of 4, IPAP max of 20, PS Max 8
I had a lot of difficultly falling asleep since the IPAP started at 6. I felt like I wasn't getting enough air being used to 10cm. I notice that my 90% IPAP was 9. I tried several weeks at 8cm on my old machine and did not feel like I was suffocating, and the aerophalgia didn't exist (got the areophalgai symtoms around 9.5 STRAIGHT CPAP).
My real question: Would increasing the EPAP min to 6, allow the IPAP to be a minimum of 8 and reduce my feeling of suffocation, or should I just try to get used to it? Also usually my VS is .1 to 0, should I be concerned with 5.9?
Even thought I had difficulty getting to sleep and woke up several time I do feel a bit more alert.
