An oropharyngeal airway is a medical device used to maintain an open airway in patients who are unconscious or unable to breathe effectively on their own. It is a curved plastic tube that is inserted into the mouth and extends into the throat, preventing the tongue from blocking the airway. This device is commonly used in emergency situations and during anesthesia. The oropharyngeal airway comes in various sizes to accommodate different patients, and it is important to select the correct size for effective use. Proper insertion technique is crucial to avoid causing discomfort or injury to the patient.
