Ultrasonographic Detection of Airway Obstruction in a Model of Obstructive Sleep Apnea

Ultrasound International Open, 2017
Purpose Obstructive sleep apnea (OSA) is a common clinical disorder characterized by repetitive airway obstruction during sleep. The gold standard for diagnosis of OSA, polysomnogram (PSG), cannot anatomically localize obstruction. Precise identification
