Which hemostatic method is commonly used for non-compressible bleeds in combat?

• A. Hemostatic dressings alone without pressure
• B. Direct pressure only
• C. Hemostatic dressing applied with minimal pressure
• D. Hemostatic dressings (e.g., Combat Gauze) applied with firm pressure

Answer: (D)

When a bleed cannot be compressed by packing tissue or a tourniquet, the goal is to tamponade the wound and accelerate clot formation with a hemostatic dressing. Dressings like Combat Gauze combine a hemostatic agent with gauze, and they work best when you pack the wound and apply firm pressure over them. The firm pressure helps push blood into the dressing, compress the vessel, and keep the hemostatic agent in place long enough to kickstart clot formation. This approach is more effective for non-compressible bleeds because it creates a stable clot and reduces continued blood loss, even though the wound can’t be squeezed shut.

Using the dressing with only minimal pressure won’t provide enough mechanical tamponade or force the agent into the wound bed, and relying on direct pressure alone is often inadequate for non-compressible bleeds where the injury isn’t easily compressed. Hemostatic dressings applied without sufficient pressure simply don’t activate to their full potential, and they won’t control bleeding that continues from deep or cavity wounds.
