In emergency care, what does the acronym "ABC" refer to?

In emergency care, the acronym "ABC" stands for Airway, Breathing, Circulation. This sequence is fundamental when addressing life-threatening situations.

The reason "Airway" is placed first is that ensuring a clear airway is critical; without it, a person cannot breathe properly, compromising oxygen supply and leading to rapid deterioration. After confirming the airway is open, the next step is to assess "Breathing." This involves checking if the patient is breathing adequately on their own. Lastly, "Circulation" addresses the need for effective blood flow, which includes checking for a pulse and assessing blood pressure. Proper circulation is essential for maintaining oxygen delivery to vital organs.

This systematic approach helps healthcare providers swiftly identify and manage potentially life-threatening conditions, making it a cornerstone of basic life support and emergency response protocols.
