What does "ABC" stand for in basic life support?

The term "ABC" in basic life support refers to "Airway, Breathing, Circulation." This sequence is critical in emergency medical situations, as it provides a systematic approach for assessing and managing a patient who may be experiencing a life-threatening condition.

Initiating with "Airway" emphasizes the need to ensure that the airway is clear and unobstructed, allowing for adequate airflow to the lungs. The next component, "Breathing," addresses the patient's ability to breathe or the need for rescue breaths or other interventions if breathing is inadequate. Lastly, "Circulation" focuses on assessing the patient's perfusion and the efficacy of their heart's pumping action, which could include chest compressions if there is no pulse.

Understanding this foundational sequence is essential for anyone involved in providing emergency care, as it helps to prioritize immediate life-saving interventions and guides responders in performing basic life support effectively.
