Change in peak expiratory flow rate after the head-tilt/chin-lift maneuver among young healthy and conscious volunteers

摘要

ObjectiveThe head-tilt/chin-lift (HT/CL) is a simple, routinely used maneuver to open the upper airway. Changes in the peak expiratory flow rate (PEFR) before and after the HT/CL maneuver have not been evaluated among conscious volunteers who are regarded as a control cohort.
