What is described as the first step of circulation in casualty care?

• A. Pack wounds not treatable with a tourniquet with combat gauze and hold pressure for 3 minutes and then apply a pressure bandage
• B. Elevate the limb and apply cold therapy
• C. Apply a tourniquet immediately
• D. Begin intravenous access before bleeding control

Answer: (A)

Circulation in casualty care focuses on stopping bleeding to keep blood flowing to vital organs. The fastest, most reliable way to do this is to apply direct pressure to the wound with dressings. If the wound isn’t treatable with a tourniquet, the next best step is to pack it with combat gauze and hold firm pressure for about three minutes to allow clotting, then apply a pressure bandage to maintain that pressure and protect the wound. This approach directly tackles the active bleed and sets up stable conditions for other treatments.

Elevating the limb and cold therapy don’t stop the bleed right away, and starting an IV before bleeding is controlled wastes time. A tourniquet isn’t always applicable, so when it isn’t, direct pressure with gauze packing followed by a pressure bandage is the appropriate first move in the circulation phase.
