C flex effect on pressure.

I have read on this forum several times that using C-flex is like lowering the pressure a couple of points. I assume then that a pressure of 13 with a c-flex setting of 2 would be about the same as a pressure of 12 with c-flex set on one or 11 with no c-flex. Would that be an accurate assumption. Any thoughts on which one of those three settings would be less likely to cause air pumped into the stomach?

Surely someone has tested this theory out in practice. If no one has I guess I will ....but I might as well save myself 3 weeks of testing if someone else has already done it.

I have a machine with C-Flex. Please correct me if I am wrong (today's been a long day), but if your pressure is 13cm and you have the C-Flex on "3", then you are exhaling against 10cm of pressure, "2" is 11cm of pressure and "1" is 12 cm of pressure. Keep in mind that C-Flex 'assists' you with exhaling and doesn't change your therapy pressure, overall.

I know the seasoned vets of the site will have some better ideas, but for me these work:
Keeping your mouth shut, keeps it from drying out and having to produce more saliva to compensate. You swallow, you get bloated.
Breath through your nose and not your mouth (if you have a full face mask).

**EDIT**

Ok, I just saw where you updated your equipment. ResMed doesn't have C-Flex, but a smilar feature called EPR, that is what you will need to adjust, but I don't know how the setting relates to the pressure on those machines. I just know a little about Respironics.

Nope. That's only with ResMed EPR. C-Flex drops the pressure ever so slightly at the beginning of the exhale process to ease the exhale but does not drop the pressure a full cm. number equal to the EPR setting like ResMed does.
You should not have to compensate for it by increasing your pressure.

Thanks Den...that's what I wanted to know.

Thanks. I had them backwards. Told you it was a long day.
