What does 'C' represent in the MARCH protocol?

In the MARCH protocol, 'C' specifically refers to Circulation, which highlights the importance of treating shock and controlling bleeding in trauma care. This step is critical because, after establishing the Airway and ensuring Breathing is adequate, it is essential to manage any circulation issues that may arise from traumatic injuries. Controlling bleeding reduces the risk of hypovolemic shock, which can rapidly become life-threatening if not addressed promptly. Effective circulation management includes applying direct pressure to wounds, utilizing tourniquets when necessary, and other interventions aimed at stabilizing the patient's hemodynamic status.

This focus on circulation is central to trauma care because loss of blood can compromise vital organ function, making it imperative to act swiftly and effectively. The other options do not accurately capture the intent of the 'C' in MARCH, as they refer to different aspects of trauma management that are not represented by this specific letter in the protocol.
