A Guedel airway, also known as an oropharyngeal airway, is a medical device used to maintain the patency of the upper airway. It is a curved, rigid plastic tube with a flange or bite block at one end and an open end at the other. The purpose of the Guedel airway is to prevent the tongue from obstructing the airway and to facilitate the passage of air to and from the lungs. The Guedel airway is available in different sizes to accommodate various patient age groups and anatomical variations. It is commonly used in emergency situations, during anesthesia administration, or in cases where a patient is unconscious or unable to maintain an open airway on their own. To use a Guedel airway, the curved portion is inserted into the patient's mouth, with the flange positioned outside the mouth to prevent the airway from being pushed too far in. The Guedel airway helps to keep the tongue from obstructing the throat and allows for the unobstructed flow of air.
