The Influence of Head and Neck Position on Oropharyngeal Leak Pressure and Cuff Position with the Flexible and the Standard Laryngeal Mask Airway

Abstract

There are small changes in oropharyngeal leak pressure but no changes in cuff position in different head and neck positions for the flexible and standard laryngeal mask airways. Oropharyngeal leak pressure may be improved by head and neck flexion and by avoiding extension.
