When should an oropharyngeal airway be used?

An oropharyngeal airway is a medical device used to maintain or open a patient's airway by preventing the tongue from obstructing the oropharynx. It is specifically designed for unconscious patients who are unable to protect their airways due to a lack of gag reflex. When a patient is unconscious, there is a risk that the tongue can fall back and block the airway, leading to respiratory distress. The oropharyngeal airway helps to keep the airway open by positioning the tongue forward.

In contrast, the use of this airway in conscious patients is contraindicated; conscious patients have a functioning gag reflex, and inserting an oropharyngeal airway could trigger choking and vomiting.

Additionally, oropharyngeal airways are not limited to use for infants or only during surgical procedures. They can be utilized in various medical emergencies and by healthcare professionals treating unconscious adults as well. Thus, the application of an oropharyngeal airway is suited for unconscious patients, making it the correct choice.
