What does "C" stand for in P-MARCH-P?

The letter "C" in P-MARCH-P stands for "Circulation," which is a critical component in the TCCC protocol. This step emphasizes the importance of assessing and managing the casualty's circulatory system to ensure that blood flow is adequate. In tactical situations, rapid assessment of circulation is key to identifying any life-threatening hemorrhages that need immediate attention. By effectively managing circulation, such as through the application of tourniquets or direct pressure to control bleeding, a corpsman can help prevent shock and increase the chances of survival for the injured individual. This step is crucial for optimizing the casualty’s physiological stability before more advanced medical treatment can be administered.
