Basic airway management is a concept and set of medical procedures performed to prevent and treat airway obstruction and allow for adequate ventilation to a patient's lungs. [1] This is accomplished by clearing or preventing obstructions of airways. Airway obstructions can occur in both conscious and unconscious individuals.
The gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall. Touching the soft palate can lead to a similar reflex response. However, in that case, the sensory limb of the reflex is the CN V (trigeminal nerve). In very sensitive ...
As infants get closer to one year old, the gag reflex moves posteriorly, closer to the laryngeal vestibule. This allows food to move closer to the laryngeal vestibule before triggering a gag. Parents following BLW are advised to avoid classic “choking hazards” or airway shaped foods: whole grapes, coin-shaped slices of hotdogs, cherry ...
An NPA is often used in patients who are conscious or have an altered level of consciousness [6] where an oropharyngeal airway would trigger the gag reflex. [7] [8] The use of an NPA is contraindicated when there is trauma to the face, especially the nose or if there is a suspected skull fracture. [9]
They are the artificial airways of choice in patients who are conscious and have intact gag reflexes because they are less likely to stimulate the gag reflex than oropharyngeal airways (OPAs). [4] [2] NPAs can also be used in other sitations where OPAs cannot, such as in patients with restricted mouth opening or oral trauma. [2]

Oropharyngeal airways are indicated only in unconscious people, because of the likelihood that the device would stimulate a gag reflex in conscious or semi-conscious persons. This could result in vomiting and potentially lead to an obstructed airway. Nasopharyngeal airways are mostly used instead as they do not stimulate a gag reflex.
