  Purpose: Continuous positive airway pressure (CPAP) is the accepted therapy for obstructive sleep apnea (OSA). An expiratory pressure relief technology called C-Flex+ has been developed to improve the comfort of CPAP therapy. It provides a 2 mbar lower exhalation pressure and an additional flow-based pressure relief at the beginning of exhalation. The following study was conducted to investigate whether C-Flex+ was as effective as CPAP in treating OSA, and the patients’ preference. Methods: 60 newly diagnosed patients with OSA completed this double-blind controlled crossover-study. Patients were randomized to one night of C-Flex+ and one of CPAP under full attended polysomnography (PSG). A comfort visual analog scale (VAS) ranging from 0 to 10, with 10 being the highest comfort, was completed by all patients immediately after each PSG... View More»
