An interventional study of CPAP (REMstar (Respironics)) in Obstructive Sleep Apnea, sponsored by Kyoto University, Graduate School of Medicine. Completed at 1 site in Japan. Open to participants aged 20 Years and older. Per ClinicalTrials.gov, last updated 2011-12-01.

The purpose of this study is to compare the treatment adherence and effects in three modalities of Continuous Positive Airway Pressure Treatment for Obstructive Sleep Apnea.
Obstructive sleep apnea (OSA) is a common disorder that is associated with substantial morbidity, including excessive daytime sleepiness, hypertension, and cardiovascular disease. Although Continuous Pressure Airway Pressure (CPAP) is effective treatment of objective and subjective complaints, adherence to CPAP therapy is suboptimal. Recently, pressure-relief CPAP (C-flex,A-flex; Respironics; Murrysville, PA) is available. The present study is single-blind,prospective, randomised, crossover study to compare the adherence and effects of therapy with C-flex, A-flex, and autoadjusting CPAP after 3 months of CPAP treatment.
Additionally, after 3 months of CPAP treatment, the patients who treated with C-flex and A-flex will crossovered, we will acess to change of adherence and effects of CPAP treatment.

Device: CPAP (REMstar (Respironics))
Pressure-relief CPAP treatment may reduce the sensation of breathing against high pressure without causing the upper airways to collapse and improve adherence.
