What is a CPAP with C-Flex?
CFLEX is a technology patented by Respironics Corporation several years ago. CFLEX is a comfort option that can be turned on or off. If turned on, it will decrease pressure during exhalation, by up to 1, 2 or 3cm of water pressure. A setting of CFLEX translates, literally, to the amount of pressure decreased during exhalation – i.e. a CFLEX of 2 means the pressure given during inhalation will drop by approximately 2cm h20 during exhalation. This option is of great assistance to new users of CPAP therapy in particular. During the first couple weeks of therapy, it can be a challenge to adjust to the sensation of a consistent pressure – CFLEX goes a long way in easing the CPAP user into this new way of breathing. The same technology in the ResMed product is called Expiratory Pressure Relief, or EPR.
