What should be performed as the seventh step in "Circulation" according to P-MARCH-P?

In the context of Tactical Combat Casualty Care (TCCC), P-MARCH-P is a mnemonic used to prioritize the steps taken in managing a casualty. The proper sequence is critical to ensure effective care, especially in combat situations where speed and accuracy can significantly impact survival.

The "Circulation" component of P-MARCH-P focuses primarily on assessing and managing potential hemorrhage and ensuring adequate blood flow. The seventh step specifically involves a groin examination. This step is essential as the groin area contains major arteries, and trauma to this region can lead to significant blood loss that may not be immediately visible. By examining this area, a corpsman can identify any potential hemorrhage from the femoral artery, which is crucial for promptly managing and controlling severe bleeding.

Performing a groin examination can lead to early intervention, such as applying a tourniquet or direct pressure as needed, thereby addressing one of the most critical components of trauma care – controlling hemorrhage. This assessment is vital in the context of life-saving measures, making it a logical and important step in managing circulation during casualty care.
