The CoTCCC is, in my opinion, the definitive source of evidence-based medical recommendations for traumatic injury, and I’ve been fortunate to train with some true professionals who have both military and civilian paramedic trauma experience.

If I recall correctly CoTCCC has approved the SOFTT-W, CAT, and SAM XT. I’ve used all three in training, The SOFTT-W is best for buddy-aid. The CAT and SAM XT work for buddy-aid and are superior for self-aid.

CoTCCC also recommends against the use of tampons for penetrating injuries. You’re better off using compression bandages, and/or packing the wound with gauze, or better still one of the approved hemostatic gauzes.
