A-Flex and C-Flex in the Respironics Auto - One or Both?

Thanks xyz.

Although I did know what the two technologies are supposed to do, knowing how they feel is another matter altogether.

I know that I tolerate C-Flex well, and I even like it. But I have never used A-Flex, though I have read posts where others have. Occasionally I see a post where the user says they do like A-Flex, or they do not. Without knowing, having both available on the sane machine is great.

Though I still can't figure out why Respironics is selling the M-Series with C-Flex when the A-Flex machine already has it.

C-Flex™ Pressure Relief Technology

C-Flex pressure relief technology makes sleep therapy more comfortable by reducing pressure at the beginning of exhalation and returning to therapeutic pressure just before inhalation. The level of pressure relief varies based on the patient’s expiratory flow and which of the three C-Flex settings has been selected.

A-Flex® Pressure Relief Technology

A-Flex is designed to work with our clinically proven auto CPAP algorithm to improve comfort even more by matching pressure delivery to the patient’s entire breathing cycle. Like C-Flex, A-Flex provides flow-based pressure relief at the beginning of exhalation. Like Bi-Flex, A-Flex softens the pressure transition from inhalation to exhalation to provide additional comfort in an auto-CPAP mode. The pressure profile mirrors the patient’s breathing, and with the auto algorithm intelligence, it will respond to the patient’s therapeutic need throughout the sleep session.

I've been using the RemStar Auto A-Flex for a while now (I'm new to the CPAP scene), and I've found I can't stand the A-Flex! A-Flex makes the mask feel like it's humping my face Not pleasant. C-Flex is just fine for me, though.

Yeah, the Activa mask tends to do that up/down movement. More noticeable the more difference there is between inhale and exhale pressures. That "humping" is unique to the Activa. I've seen it described as "like a lovesick octupus doing pushups on your face."

The Activa is a very good mask for sealing well. The bellows cushion that makes it seal so well is why it also has that little quirk.
