The Articulated Oral Airway as an Aid to Mask Ventilation

Completed · Not applicable

Conditions studied: Mask Ventilation, Airway Obstruction Upper, Airway Management

In brief

The Articulating Oral Airway (AOA) is a novel oral airway which actively displaces the tongue, allowing for a greater cross-sectional area for mask ventilation. The investigators hypothesize that, in patients with predictors for difficult mask ventilation, the AOA will be non-inferior to the Geudel oral airway in terms of expired tidal volumes.
