When a non-rebreathing mask is intolerable for the patient. Patients with physical injuries, chronic airway obstruction, cluster headaches, and smoke inhalation use non-rebreather masks.
<h3>When is it appropriate to employ a nasopharyngeal airway?</h3>
A patient's nostril is entered with a thin, transparent, flexible tube called a nasopharyngeal airway (NPA). Bypassing upper airway congestion at the level of the nose, nasopharynx, or base of the tongue is the goal of the NPA. In order to avoid obstruction, it also prevents the tongue from falling backward against the pharyngeal wall.
<h3>Which of the following patients can be treated with nasopharyngeal airways?</h3>
For patients with an intact cough and gag reflex, NPAs can be used in patients who are aware, semiconscious, or unconscious, unlike oral airways.
