What does the acronym ABC stand for in basic life support?

The acronym ABC in basic life support stands for Airway, Breathing, Circulation. This sequence is critical because it outlines the initial steps one must take when assessing and providing care to a patient who may be experiencing a life-threatening emergency.

Airway refers to ensuring that the patient’s airway is clear and unobstructed, which is essential for allowing air to reach the lungs. Breathing involves assessing whether the patient is breathing adequately and taking appropriate action if they are not. Circulation pertains to checking for a pulse and ensuring that blood is circulating properly; without effective circulation, vital organs can quickly become deprived of oxygen.

Understanding this sequence is foundational for anyone providing basic life support, as it allows responders to prioritize their interventions and effectively stabilize individuals in critical situations.
