**7.2 Extraglottic devices for ventilation**

Extraglottic airway devices are used to establish an airway for oxygenation and ventilation without entering the trachea. They are important tools that are frequently used in the pre-hospital setting, the emergency department, the operating room, and other settings [26, 29].

These devices are useful in cases of DA management in patients who cannot be intubated or ventilated. Contraindications to the use of extra-glottic airway devices include obstructive airway diseases, traumatized airways, gag reflex, etc.

These types of devices should be used under sedation to reduce pharyngeal spasms/reflexes that can impair ventilation (**Table 5**).
