Which patient should receive a nasopharyngeal airway?

The appropriate use of a nasopharyngeal airway is indicated in situations where a patient is unable to maintain a patent airway but still has an intact gag reflex. In the case of the 66-year-old male with snoring respirations, the presence of the gag reflex suggests that he is still able to protect his airway, making the nasopharyngeal airway a suitable choice to alleviate obstruction caused by the tongue or other soft tissue structures.

This airway adjunct is particularly effective when the patient is semi-conscious or has diminished consciousness but can still respond to stimuli, as it allows for ventilation while the patient maintains the ability to protect their airway if necessary. The snoring respirations suggest that there is likely some form of obstruction, and introducing a nasopharyngeal airway can help alleviate this while avoiding further complications of intubation or other more invasive measures.

Conversely, when considering the other options, they present scenarios where the use of a nasopharyngeal airway would not be appropriate. For example, an unconscious patient without a gag reflex may have the potential for airway loss due to the loss of reflexes, and a more secure airway measure would be necessary. In another case, the patient is breathing adequately and is conscious,
