NPAs are passed into the nose and through to the posterior pharynx. NPAs do not cause patients to gag and are, therefore, the best airway adjunct in an awake patient and a better choice in a semiconscious patient that may not tolerate an oropharyngeal airway due to the gag reflex. NPAs are also helpful when a patients mouth is difficult to open or access, for example, in cases of trismus or angioedema. While NPAs are airway adjuncts for ventilation and oxygenation in patients who are difficult to ventilate and oxygenate, they only act as a bridge to either a secure airway via endotr...
