What is the first step in the ABCs of first aid?

The first step in the ABCs of first aid is to ensure that the airway is clear and accessible. This is crucial because an obstructed airway can prevent air from reaching the lungs, making it impossible for the individual to breathe effectively. In emergent situations, prioritizing the airway is vital; if the airway is not secured, subsequent efforts to address breathing and circulation may be ineffective.

Ensuring that the airway is open can involve techniques such as the head-tilt, chin-lift maneuver or other methods to remove any obstructions. Once the airway is secured, responders can then assess breathing and circulation as the next important steps in providing effective first aid.
