That can feel disconcerting to some people, causing them to feel like the machine is trying to "force" them to start inhaling again before they're ready to. Some people begin breathing faster and faster, trying to keep up with what it feels like the machine is doing.
Simple, clear explanation, RG. I realize, now, why I felt like the machine was trying to regulate my breathing, particularly with nasal pillow masks because I could hear so loudly the air coming into my nasal passages. It is not nearly as persuasive with nasal or full-face masks because the air flow is not concentrated in the nasal passages.
If the C-flex is too disconcerting, it can be disabled. Then, if the exhalation resistance is too much, the ramp feature can be used to start at a pressure as low as 4 cm., so that sleep occurs before the machine reaches full prescribed pressure (0-30 min.).

I also feel I should mention that there are three levels of C-Flex + that you can select, so if a 3 is too aggressive for you and you feel like its trying to force you to breathe a certain way, drop the number down to a 1 or a 2 and you will find that its more passive. I'm currently using the setting on a 2. ALSO, as Jerry stated, you can use the ramp feature to help you fall asleep before it gets to full pressure and then your brain wont be actively trying to change your breathing patterns because you are focusing on what the machine is doing too much.
