Change in End-Expiratory Lung Volume During Sleep in Patients at Risk for Obstructive Sleep Apnea

摘要

Study Objectives: As lung volume decreases radial traction on the upper airway is reduced, making it more collapsible. The purpose of this study was to measure change in end-expiratory lung volume (EELV) following sleep onset and to evaluate the relationship between change in EELV and sleep-disordered breathing.
