When should an oropharyngeal airway be used?

An oropharyngeal airway is specifically designed for use in unresponsive patients who do not have an active gag reflex. This is crucial because the device can help maintain an open airway by preventing the tongue from obstructing the airway. In patients who are unresponsive, the risk of airway blockage due to tongue displacement is significant; therefore, inserting an oropharyngeal airway establishes a clear passage for airflow.

In contrast, using this type of airway in awake patients with a gag reflex or responsive patients can trigger vomiting or laryngospasm, which can further compromise the airway. Additionally, in patients with severe facial trauma, there might be anatomical concerns that make the use of an oropharyngeal airway inappropriate as it could exacerbate injuries or lead to complications. Thus, the optimal context for the use of an oropharyngeal airway is indeed in unresponsive patients who lack the gag reflex.
