What does the "C" in ABC stand for?

In the context of airway, breathing, and circulation, the "C" specifically refers to Circulation. This element is critical in the assessment and management of a patient's condition during emergencies or medical evaluations. Maintaining effective circulation ensures that oxygen-rich blood is delivered to vital organs and tissues, which is essential for survival.

When assessing circulation, key factors include checking the patient's pulse, skin color, temperature, and capillary refill time. Assessing circulation aids in identifying issues like shock or cardiac arrest, thereby guiding appropriate interventions. Recognizing that circulation is fundamental in the ABC framework emphasizes the importance of maintaining perfusion and preventing further complications in a medical emergency.
