Insertion of a nasopharyngeal airway—a soft rubber or latex uncuffed catheter—establishes or maintains a patent airway. This airway is the typical choice for patients with airway obstruction or the risk for developing airway obstruction when conditions such as a clenched jaw or oral problems prevent placement of an oral airway.¹ It’s also used to protect the nasal mucosa from injury when the patient needs frequent nasotracheal suctioning.

The airway follows the curvature of the nasopharynx, passing through the nose and extending from the nostril to the posterior pharynx. The bevel-shaped pharyngeal end of the airway facilitates insertion, and its funnel-shaped nasal end helps prevent slippage.

Insertion of a nasopharyngeal airway is preferred when an oropharyngeal airway is contraindicated or fails to maintain a patent airway. A nasopharyngeal airway is contraindicated if the patient has a pathologic nasopharyngeal deformity. An oropharyngeal airway is preferred when a basal skull fracture or severe coagulopathy is present or suspected.¹
