This piece of equipment is utilized by certified first responders, emergency medical technicians, paramedics, anesthesia providers, and other health professionals when tracheal intubation is either not available, not advisable or the problem is of short term duration.
[citation needed] 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.
In general, oropharyngeal airways need to be sized and inserted correctly to maximize effectiveness and minimize possible complications, such as oral trauma.
Once contact is made with the back of the throat, the airway is rotated 180 degrees, allowing for easy insertion, and assuring that the tongue is secured.
[1] Use of an OPA does not remove the need for the recovery position and ongoing assessment of the airway and it does not prevent obstruction by liquids (blood, saliva, food, cerebrospinal fluid) or the closing of the glottis.
