• 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.
