Investigation of a Novel Oropharyngeal Airway: The ManMaxAirway

Status unconfirmed · Not applicable

Conditions studied: Airway Obstruction, Respiratory Complication

In brief

Guedel pattern or oropharyngeal airways (OPA) maintain an open oral airway in unconscious or semi-conscious patients by preventing the tongue from covering the epiglottis, but OPA placement carries a risk of inducing gag reflex and vomiting. Although various sizes are available, the design of the OPA has undergone little change since its introduction in the 1920s. The purpose of this study is to determine the utility of a novel airway device, the ManMaxAirway (MMA), as an alternative to the OPA.
