Supraglottic airways (SGAs) are devices used to secure the airway in an adult patient who is unable to maintain an open airway. SGAs are also referred to as extraglottic or periglottic devices. These devices are often used in patients with difficult airways and those who have failed initial attempts at tracheal intubation.
Supraglottic airways are devices used to provide an airway during emergencies. They can be inserted into the mouth and throat, in contrast to endotracheal tubes (ETTs) that go down into the patient’s upper airway. Supraglottic airways may be inserted to secure an adequate airway for a patient who cannot breathe or has an inadequate cough reflex.
