:- An oropharyngeal airway (also known as an oral airway, OPA or Guedel pattern airway) is a medical device called an airway adjunct used in airway management to maintain or open a patient's airway.
:- It does this by preventing the tongue from covering the epiglottis, which could prevent the person from breathing. When a person becomes unconscious, the muscles in their jaw relax and allow the tongue to obstruct the airway.
:- The OPA is sized by measuring from the center of the mouth to the angle of the jaw, or from the corner of the mouth to the earlobe. The mouth is opened using the “crossed or scissors” finger technique.
