C-Flex/A-flex, benefits?

I understand that C-Flex/A-flex can improve comfort during your therapy, which promotes compliance.

But I was wondering if it effects your therapy in other ways.

For instance, does it effect the AHI numbers for some? Improve snoring rates??

I believe that it only makes it easier for you to start usinfg the cpap if you have a high setting. For example my setting is 20cm and it's some what hard to get used to using cpap begining at that pressure. With c-flex or a-flex you can start out at about 4cm and it willslowly increase to 20cm if your pressure is that high.

The Flex technologies are "comfort" features and should not affect your numbers......AHI or snoring.

That's ramping I believe. C-Flex/A-Flex has a choice of 1-3 (or off). 3 being the most expiration relief.

Ok, good to know.

TNT - ramping is separate from c-flex and a-flex .... it's used for the first XXX minutes (set on panel) to start at a pressure lower than the lowest pressure in the APAP range. For example, if my APAP range were 10-15 but I found 10 a bit high to start, then I'd set ramp to start at maybe 6 or 7. It would then increase up to 10 and for the rest of the session the pressure would vary between 10 and 15.

C-Flex and A-Flex, on the other hand, provide pressure relief when you exhale but I think (not certain) that the pressure drop is not related to ramp.

I disagree. I was started on 6cm pressure (which turned out to wrong, too low) I found it very hard to breath out against that on a machine that had to exhalation relief. I eventfully updated to a machine with C-Flex and right away started sleeping about an hour longer each night.

Switching from cpap to A-Flex (relief setting 3) brought these benefits for me:

1)Less mouth breathing
2)Less swallowing air (aerophagia)
3)Fewer mask leaks

Interesting, thanks for your response.
