Protection of the airway and the risk of aspiration depend on how well the device isolates the lungs from the stomach contents. Endotracheal intubation with a cuffed tube creates a seal below the vocal cords, blocking gastric contents from entering the lower airway and reducing aspiration risk, especially during ventilation. Supraglottic devices sit above the glottis and don’t seal the trachea as effectively, so if regurgitation occurs or vomiting happens, material can reach the lungs despite the device, and the risk can be heightened during or after airway management when ventilation is active. Because of this, regurgitation and aspiration are more likely to occur during or after placing and using supraglottic devices than with endotracheal intubation. Endotracheal intubation lowers, but does not completely eliminate, aspiration risk, and the other options don’t reflect the comparative protection these devices provide.
