Efficacy of Simple Continuous Positive Airway Pressure on Patients With Obstructive Sleep Apnea

Study Design: A randomized, cross-over and double blind study . Objective: To investigate the efficacy of simple device of continuous positive airway pressure (CPAP) in the treatment of obstructive sleep apnea (OSA). Methods: A randomized, cross-over and double blind study would be performed on 100 OSA patients using both simple CPAP and traditional CPAP during overnight polysomnography. Pressure for CPAP treatment would be manual titrated. The sleep apnea hypopnea index (AHI), arousal index (ArI), Oxygen desaturation Index (ODI), sleep structure and the preference of CPAP model were to be observed.
