What does the acronym ABC stand for in first aid assessment?

The acronym ABC in first aid assessment stands for Airway, Breathing, and Circulation. This sequence is critical for prioritizing the care of a person in an emergency situation.

Starting with the airway, it is essential to ensure that the person’s airway is clear to facilitate breathing. If the airway is obstructed, the individual cannot receive the necessary oxygen, which is vital for survival. After confirming that the airway is clear, the next step is to assess breathing. This involves checking for the presence of normal, effective breathing and initiating rescue breaths if necessary. Finally, circulation must be evaluated, which includes checking for the presence of a pulse and controlling any significant bleeding. By following this order, rescuers can systematically ensure that the most critical functions of the body are addressed first, significantly increasing the chances of survival and recovery.
