What is the first step in assessing the airway in a first aid scenario?

In a first aid scenario, the first step in assessing the airway is to use the head tilt/chin lift maneuver. This technique is crucial because it helps to open the airway by moving the tongue away from the back of the throat, which can obstruct airflow, especially in an unconscious or semi-conscious person. By tilting the head back and lifting the chin, you create a straight path for air to enter and exit the lungs, which is essential before any further assessment or intervention can occur.

Administering CPR is only appropriate if the individual is unresponsive and not breathing or not breathing normally, but it should not be the first action taken without ensuring a clear airway. Calling for medical help is an important step in a first aid situation, but it should follow immediate airway assessment. Checking for a pulse is relevant when assessing circulation; however, it is a secondary step that follows the assessment of the airway. Therefore, ensuring that the airway is clear takes precedence as the first action to support the victim effectively.
