What is the best way to assess a victim's airway?

The best way to assess a victim's airway is to tilt the head back and lift the chin. This maneuver, known as the head-tilt, chin-lift technique, is effective because it opens up the airway by repositioning the tongue and using gravity to prevent it from blocking the airway. In an unconscious person, the tongue can fall back into the throat, obstructing airflow. By tilting the head back and lifting the chin, you create a clear passage for air.

This method is widely taught in CPR and first aid courses because it's safe, straightforward, and essential before checking for breathing or administering rescue breaths. Ensuring an unobstructed airway is a critical first step in any resuscitation effort, as effective ventilation cannot occur if the airway is blocked.

Other techniques mentioned would be inappropriate in this context. Keeping the head down does not facilitate airflow, while pushing the chin down can worsen airway obstruction. Checking for breathing without assessing the airway first may lead to ineffective rescue efforts if the airway is not clear. Therefore, employing the head-tilt, chin-lift method is the standard practice in airway assessment.
