In first aid terminology, what does ABCs stand for?

• A. Airway, Breathing, Circulation
• B. Airway, Bypass, Circulation
• C. Airway, Breathing, Compression
• D. Airway, Blood, Circulation

Answer: (A)

ABCs stands for Airway, Breathing, Circulation. This order guides the priorities in a first aid response: first make sure the airway is open and clear so air can reach the lungs; if the airway is blocked, clear or reposition it as needed. Next, assess breathing and provide rescue breaths or ventilations as appropriate. Finally, address circulation by looking for signs of life or severe bleeding and, if needed, start chest compressions to maintain blood flow to the heart and brain. Keeping the airway open is the first critical step because without a clear airway, breaths can’t reach the lungs; without breathing, oxygen can’t enter the blood; without circulation, oxygenated blood can’t reach vital organs. Note that some modern CPR guidelines for adults emphasize starting with chest compressions (circulation) and then addressing airway and breathing, but the traditional ABCs remain a common framework in basic first aid.
