Hello,
I've been using my resvent ibreeze CPAP machine now for about 8 months. My leak rate and AHI were all over 25 for quite some time until I switched to a nassal pillow mask and chin strap. I've been very happy with my numbers - AHI and Leak rate are always under 5 now and sometimes <1.
However, I'm confused as to why I'm experiencing aerophagia, especially the last few weeks. Using the chin strap is what dropped my numbers to such low levels. Prior to that, with any mask I tried, numbers were over 25 to as high as 45.
I lowered my pressure from 15, to 12 to now 10. I lowered it to 10 to see if that would help curb the aerophagia. It may have helped a little but its still there. I'm just surprised being my mouth is staying closed now due to the chin strap. I am thinking that if my mouth was opening, my leak rate would be higher.
Any ideas on where to go from here?
Numbers:
Leakage - 3.5L/min
AHI - .3/h
OAI - .3/h
AI - .3/h
CAI - 0
HI - 0
SNI - 0.0
iPR - 3
