Which of the following is a method to clear the airway?

The abdominal thrust is the correct method for clearing the airway in a choking emergency. This technique, also known as the Heimlich maneuver, is effective for dislodging an obstruction from the airway of a conscious person who is unable to breathe or speak due to choking. By delivering forceful inward and upward thrusts just above the navel, the abdominal thrust creates enough pressure to expel the object blocking the airway.

In contrast, the other options do not serve this purpose. An eye wash is designed to flush out foreign substances or irritants from the eyes, a cold compress is used to reduce swelling or pain, and restoration of breath is a general term that does not specify an action for clearing an obstruction. Understanding the specific application of the abdominal thrust is crucial for effectively responding to situations involving airway blockage.
