Identifying Affecting Factors on Acceptance with CPAP on the First Night of PAP Titration in Sleep Clinic on Patients with Obstructive Sleep Apnea

This research examined the causes of low acceptance with Continuous Positive Airway Pressure Continuous Positive Airway Pressure (CPAP) especially anatomical causes and if eliminating them would result in increasing its adherence. This cross sectional study was performed on patients with moderate to severe Obstructive Sleep Apnea Obstructive Sleep Apnea (OSA) undergoing PAP titration in the sleep clinic. CPAP acceptance was evaluated by visual analog scale (VAS) about mask and sleep satisfaction and the possibility of using CPAP in the future, mask complications, physical examination of the upper airway and polysomnographic (PSG) results before and after titration. participants were divided into three groups of non-acceptant, semi-acceptant and acceptant with CPAP based on the satisfaction of the mask and sleep. There were no significant differences between groups based on age, gender, education, BMI and polysomnographic variables. With a study of mask complication, there were significant differences among groups for dry mouth, mask leakage and cold air. (p
