A Guedel Airway (also known as an oral airway, OPA or oropharyngeal airway) is a medical device called an airway used 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 relaxes and allow the tongue to obstruct the airway. 9026 GUEDEL AIRWAYS Size 0,00,000,1,2,3,4,5 Box Qty.: 100 Nos. • Single Use • Rounded edges • Bite block Colour coding • Airway path in centre
