Respironics has redesigned their sleep therapy system to give patients more of what they want, including the proven comfort of C-Flex. Respironic's patented C-Flex technology offers a more comfortable way to deliver sleep therapy by taking the work out of exhalation. C-Flex tracks and reacts to every breath throughout the night, increasing your comfort as you exhale. The new M Series platform is even easier to use, provides a small and sleek platform, and has a less obtrusive profile with tube connection in the back of the unit. This is the smallest Respironics CPAP available!
