The difference that patients feel when using C-Flex comes, in large part, from Digital Auto-Trak®. This patented algorithm precisely identifies the transition between inhalation and exhalation even in the presence of mask leak and other variables. Digital Auto-Trak helps therapy feel more natural by matching therapy to the patient's natural breathing pattern. And by matching the patient's breathing pattern, C-Flex can reduce pressure at the moment of expiration.

With three C-Flex levels, patients have the ability to select the level of pressure relief that's right for them. The amount of pressure relief will vary on a breath-by-breath basis depending on the patient's expiratory flow and the C-Flex setting. The device returns to the prescribed pressure at the end of exhalation to ensure proper therapy.
