STUDY OBJECTIVES Overnight rostral fluid shift from the legs to the neck may narrow the pharynx and contribute to obstructive sleep apnea (OSA) pathogenesis. We hypothesized that night-to-night changes in the apnea-hypopnea index (AHI) would be associated with changes in overnight rostral fluid shift. METHODS Twenty-six patients with OSA (AHI ≥10) underwent two polysomnograms 14 days apart wi...
