Clinical trials: Exercise Induced Pharyngeal Collapse
Sleep Apnea
Mechanisms of Pharyngeal Collapse in Sleep Apnea, Study C
In obstructive sleep apnea (OSA), the upper airway recurrently closes during sleep. The mechanisms that lead to airway closure are not completely understood. Models to study mechanisms of airway collapse have been proposed.
