If you come acrosson-scene of a 56-year-old female patient experiencing cardiac arrest. The first airway you should administer is the Oropharyngeal airway. Oropharyngeal airway or oral airway for short is known as a medical device considered to be an airway adjunct, which is used to open a patient’s airway and refrain it from being obstructed by the tongue. It prevents the tongue from covering the epiglottis, which could hinder the patient from breathing, when a person turns unconscious, the muscles in the jaw relaxes and allows the tongue to block the airway.
