What does 'C' in the MARCH protocol assess?

The 'C' in the MARCH protocol specifically stands for Circulation, which emphasizes the importance of assessing blood flow and identifying any life-threatening hemorrhage. This assessment involves checking for a pulse, evaluating skin perfusion, and determining if there are any visible signs of bleeding that need immediate control.

Effective management of circulation is crucial in trauma situations, as severe bleeding can lead to shock and death within minutes if not addressed promptly. By focusing on circulation, responders can prioritize interventions such as applying a tourniquet or direct pressure to control hemorrhage, making it a critical component of the primary assessment in the MARCH protocol. This attention to circulation also includes the overall evaluation of the patient's hemodynamic stability, ensuring that they are receiving adequate blood flow to vital organs.
