newbie here. equipment in my signature (I hope:>). I'm having problems with air in my stomach when I wake up and a slight headache. I went to my doctor (actually saw the nurse practitioner) and she said it was because on my exhale, some of the exhale was going into my stomach. she changed the c-flex from 2 to 3 and said this should fix the problem. that said, I saw another post where someone said that the different C-Flex settings were all 2cmH20 and the difference was how quick it got to that pressure. However, the usermanual states that 3 allows the most relief. so the manual and the post offer differing thoughts on which setting offers more relief. the reason I'm bringing this up is sincerely not to get folks upended about who is right and who is wrong; but rather the 3 setting didn't really work for me. I'm tempted to try the 1 setting in hopes that might be better; but frankly I'm nervous about being worse if the manual is correct in it's wording.
on the other hand, it could be something completely different - and I'd welcome comment on that.The Flex settings all provide about 2 cmH2O pressure relief, settings 1-3 affect the timing of the relief with 1 being fastest and 3 being slower. Since you want the machine to switch to lower pressure faster for exhale relief, use setting 1.
btw - I've never quite experienced this air in my stomach feeling. it's not like having gas; but rather higher up and quite uncomfortable. it's not the minor burping; but I'm having to force some rather large burps to get rid of the bloated feeling.
thank you for any comments / help.
the new kid on the block....
