What can converting a tourniquet to a pressure dressing potentially save?

• A. The casualty's life
• B. The casualty's limb
• C. The casualty's vision
• D. The casualty's blood supply

Answer: (B)

Converting a tourniquet to a pressure dressing is a critical step in managing severe extremity hemorrhage after the initial bleeding has been controlled. The primary reason this transition can potentially save a casualty's limb is that a tourniquet, while very effective for stopping life-threatening bleeding, can also restrict blood flow significantly. If applied for an extended period, especially improperly or without transitioning to a less restrictive treatment, a tourniquet can lead to tissue ischemia or necrosis, which can ultimately result in limb loss. By switching to a pressure dressing, you allow some blood flow to return to the limb while still applying enough pressure to control the bleeding, thus preserving the limb’s viability. This change focuses on balancing the need to control bleeding and ensuring that the limb receives adequate blood supply to prevent damage. Therefore, the emphasis on limb preservation is crucial in trauma care and emergency response scenarios.
