Supraglottic airways are rapid, less invasive tools used to ventilate a patient when you can’t secure the airway with an endotracheal tube. They’re designed as rescue devices that buy time and maintain oxygenation while you figure out a definitive airway.

The best choice here is that you use a supraglottic airway when the endotracheal tube attempt is unsuccessful. In many EMS and hospital scenarios, you try to secure a definitive airway with intubation, but if those attempts fail or are not feasible due to patient anatomy, trauma, or poor visualization, a supraglottic device provides immediate ventilation. It acts as a bridge to a definitive airway or, in some cases, as an acceptable temporary airway when a longer-term intubation isn’t possible right away.

It isn’t appropriate to rely on a supraglottic airway as the universal first-line approach for all trauma patients, since endotracheal intubation often offers better protection against aspiration and more secure ventilation when feasible. It’s not restricted to pediatric patients, and while it can be used in children, it’s not limited to them. The key situation for its use is as a backup when endotracheal intubation cannot be accomplished.
