Oropharyngeal airways are medical devices used to maintain an open airway in patients who are unconscious or unable to breathe effectively on their own. They are typically made of plastic and come in various sizes to fit different patients. The device is inserted into the mouth and extends into the oropharynx, preventing the tongue from blocking the airway. These airways are commonly used in emergency situations, during anesthesia, or in critical care settings. Proper sizing and insertion technique are crucial to ensure effectiveness and minimize the risk of complications, such as airway obstruction or injury to the oral cavity.
