NPA vs. OPA: Clinical Applications in Emergency Airway Management
In emergency airway management, Nasopharyngeal Airways (NPA) and Oropharyngeal Airways (OPA) are essential airway adjuncts designed to maintain upper airway patency. Although both devices serve similar functions, their clinical indications differ.
NPA is inserted through the nasal passage and is suitable for patients who retain a gag reflex or are conscious or semi-conscious. It minimizes stimulation and is particularly useful in cases of restricted mouth opening or jaw clenching.
OPA, inserted orally, is primarily indicated for unconscious patients without a gag reflex. It effectively prevents tongue-related airway obstruction and is widely used in emergency and critical care settings.
