I'm Jonathan, 24 years old and from Germany. I've had my diagnosis (Severe sleep apnea with AHI 40 to 70) in 2007, so I'm using my CPAP since 6 years now.
In 2007 I've accepted this therapy method right away and started using it every night until nowadays. But since two or three years I'm having serious problems with air in my stomache, it's like I am "swalloing" air, my stomach is filled up with air. I think some of you know what I mean, since this problem is getting more popular.
Until last year I used a ResMed S8 AutoSet with first 7mbar, then after 3 years with 8mbar and with 9mbar at the end (the pressure was adjusted by the sleep doctor because I felt more sleepy symptoms again).
Since October 2012 I'm using a ResMed S9 VPAP S, because me and my sleep doctor thought we could erase the air swalloing by using a bilevel-machine. But actually it didn't work out really. I'm still having these problems and it's getting really really annoying and painful.
Does anybody have any tips on these symptoms? I've already tried many different settings with my VPAP S (Ti Max/Min, Rise Time, Backup Rate, IPAP, EPAP etc.) but either the air-swalloing-symptoms get slightly better and the therapy is not effective (if I set a low pressure) or it gets worse.
Furthermore I always read on resmed.com etc. that most of their machines have "EPR" (exhale pressure relief), but I don't find it on both of my machines, neither on the S8 nor on the S9 (yes, I've searched the clinical menu). Are there different types of the models? Some of them have EPR and some of them don't? Are there software/firmware updates available for the machines?
Thank you very much for any helping answer.
Many regards from Göttingen, Germany
