Comparison Between Auto CPAP and Fixed CPAP in Chinese Patients With OSA

Chinese University of Hong Kong

Overview

AutoCPAP would lead to better compliance than FixCPAP

A prospective, randomized crossover cohort. Study subjects consisted of patients newly diagnosed with obstructive sleep apnea (OSA) confirmed with sleep study. All are CPAP naïve. Randomization: Arm 1: auto CPAP sleep study then auto CPAP for 2 months Arm 2: fixed CPAP titration then fixed CPAP for 2 months Then switch over to the other arm Trial end after 4 months, compliance and other parameters would be compared between two arms as described in the endpoint session.
