Nasopharyngeal airway insertion

The nasopharyngeal airway (NPA) should be coated with water-soluble lubricant or anesthetic jelly. The device is then inserted along the floor of the naris into the posterior pharynx behind the tongue. Clinicians should note that the floor of the naris inclines in a caudad orientation approximately 15 degrees. The tube can be rotated slightly if resistance is encountered.
