What do the ABC's of first aid stand for?

The ABC's of first aid refer to the crucial steps that must be taken in emergencies to ensure that a patient maintains vital functions. Airway, Breathing, and Circulation represent the essential priorities in a life-threatening situation.

Airway denotes the importance of ensuring that a person's airway is clear so that oxygen can enter the lungs without obstruction. Breathing refers to the need to assess and ensure that the individual is breathing adequately. Circulation encompasses checking the patient’s pulse and confirming blood flow to prevent shock and maintain organ function.

Understanding these foundational concepts is vital in emergency situations, as they guide first responders in their initial assessment and interventions, ultimately increasing the chances of survival until professional medical help arrives. The other options, while they include some important concepts related to first aid, do not correctly articulate the essential order of operations needed to preserve life in emergencies.
