Positive airway pressure-associated epiglottis-related obstruction in adult men with obstructive sleep apnea

The authors aimed to investigate how positive airway pressure (PAP) affects ventilation and inspiratory airflow in adults with obstructive sleep apnea (OSA) who exhibit visual evidence of epiglottis-related obstruction during drug-induced sleep endoscopy (DISE). Their findings indicate that in some individuals, the presence of epiglottis-related obstruction limits the expected increases in ventilation and airflow typically associated with higher PAP levels, highlighting a potential complication in the management of OSA.
