Incidence of Sleep-disordered Breathing and Upper Airway Collapsibility in Postpartum Patients and Its Intervention
연구 개요
상태
상세 설명
After obtaining study consent, each patient underwent measurements of upper airway cross-sectional area (CSA) during daytime within 48 h after delivery. The minimum upper airway CSA was measured using acoustic pharyngometry (Eccovision Acoustic Pharyngometry; Sleep Group Solutions, Inc) in sitting, 45° elevated, and nonelevated upper body position. This method has been previously used and validated in pregnant women.
In the patients who further gave consent for the sleep study, polysomnography (PSG) was performed throughout the entire study night. Within a crossover design, patients were randomly assigned to receive first either nonelevated or 45° elevated upper body position. Position was changed after 3.5 h by a member of the team.
