In what situation is a tongue depressor commonly used during airway management?

A tongue depressor is commonly used in airway management, particularly when inserting an oropharyngeal airway (OPA) in children. The primary purpose of a tongue depressor in this scenario is to help visualize the oropharynx and to keep the tongue from obstructing the view and access to the airway.

When inserting an OPA, proper positioning and clear access are crucial, especially in pediatric patients where airway anatomy can differ from that of adults. The use of a tongue depressor allows the responder to gently push the tongue down, facilitating a more straightforward and safer insertion of the OPA.

In contrast, the other options do not typically involve the use of a tongue depressor as part of the airway management process or CPR. In adults, securing the airway often does not require a depressor; in infants, chest compressions are performed directly without the need for a visual aid; and during CPR in adults, the focus is on compressions and rescue breathing rather than visualizing the airway.
