Which airway device provides a definitive airway alternative when intubation is not possible?

• A. Oropharyngeal airway
• B. Nasal airway
• C. Endotracheal tube
• D. Laryngeal mask airway

Answer: (D)

When intubation isn’t possible, you need a device that can quickly secure an airway and allow effective ventilation without requiring a tracheal tube. The laryngeal mask airway sits over the laryngeal inlet and creates a seal that enables ventilation of the lungs without entering the trachea. It’s fast to place and requires less technical skill than intubation, making it a reliable rescue option in a cannot-intubate scenario. It acts as a bridge to a definitive airway because it maintains oxygenation and ventilation while you consider or prepare for a more secure airway if needed.

Adjuncts like the oropharyngeal or nasal airways help keep the airway open but do not seal or protect the airway, so they aren’t suitable as the primary rescue device when intubation has failed or is not possible. An endotracheal tube provides the definitive airway, but it cannot be used if intubation is unsuccessful; the laryngeal mask airway offers a practical, immediate alternative to maintain ventilation in that situation.
