What is the primary purpose of a nasopharyngeal airway?

The primary purpose of a nasopharyngeal airway is to prevent airway obstruction. This device is designed to maintain an open airway in patients who are unconscious or semi-conscious but still have an intact gag reflex. It achieves this by bypassing obstructions that may occur at the oropharynx due to the tongue or other anatomical structures.

By keeping the airway open, the nasopharyngeal airway facilitates the passage of air into and out of the lungs, effectively reducing the risk of hypoxia and respiratory distress. It is particularly useful in situations where a patient may present with altered levels of consciousness, making non-invasive management critical.

While assisting with oxygen delivery and providing supplemental ventilation are important aspects of airway management, they are secondary functions that can be complemented by the presence of an effective airway device. Ensuring an unobstructed airway is the fundamental goal, allowing additional interventions to be applied if necessary.
