• • Nasopharyngeal airways provide a conduit for airflow between the nares and the pharynx.

  • Nasopharyngeal airways prevent mandibular tissue from obstructing the posterior pharynx.

  • Nasopharyngeal airways may be used in conscious patients (unlike oropharyngeal airways).

  • Nasopharyngeal airways may be used in children with impaired consciousness or in neurologically impaired patients with poor pharyngeal tone leading to upper airway obstruction.

• • Nasal airway occlusions.

  • Nasal fractures.

  • Coagulopathy (because of the risk of epistaxis).

  • Cerebrospinal fluid leak.

  • Basilar skull fracture.

  • Adenoidal hypertrophy.

• • A nasopharyngeal airway is a soft rubber or plastic tube.

  • Nasopharyngeal airways come in various sizes ranging from 12F to 36F.

  • A shortened tracheal tube may be used as a nasopharyngeal airway.

  • Lubrication jelly.

• • Nasal bleeding.

  • When using a shortened tracheal tube instead of a soft nasopharyngeal airway, injury to the soft tissues of the nasal passages may occur because of the rigid stiff plastic.
