Nasopharyngeal Airway

A nasopharyngeal airway is an adjunct inserted into the  nasal passageway to secure an open airway. When a patient becomes unconscious, the muscles in the jaw commonly relax and can allow the tongue to slide back and obstruct the airway. This makes airway management necessary, andan NPA is one of the available tools. An NPA is often used in  conscious and semiconscious patients where an oropharyngeal airway would trigger the gag reflex.
