For decades, an axiom of care in the resuscitation of cardiopulmonary arrest was “airway first.” Airway management seeks to maintain or create an open pathway to the lungs to ensure adequate oxygenation and ventilation, commonly using the strategy of bag-valve-mask ventilation. However, because maintaining an open pathway for gas exchange is difficult with this approach and does not protect the lungs from aspiration of gastric contents, more advanced airway maneuvers are often used. These techniques usually involve endotracheal intubation or supraglottic airway placement. The latter device is inserted blindly through the mouth, sealing the hypopharynx to facilitate oxygen delivery without a direct conduit through the glottis.
