In this episode of the Survival Medicine Hour, Joe and Amy Alton, aka Dr. Bones and Nurse Amy discuss improvised tourniquets and some TCCC guidelines regarding hemorrhage under fire or in normal times. Blood clotting agents are introduced and Quikclot/Celox are compared. Plus, when should a wound be closed and when should it be treated as a open wound from beginning to full recovery? All this and more from a Survival Medicine Hour on the road, this time in Chicago, Illinois.
