Old-school thinking held that if a tourniquet were used on an extremity wound, the injured person would lose that limb. That has been shown to be incorrect, and tourniquets are now in the first-aid kits of medics on battlefields and streets worldwide. SWAT Medic B.J. Hall presents three tourniquets that he has found reliable and effective as tactical medical solutions: the Pneumatic Tourniquet, the C-A-T Tourniquet, and the SOF-T Tourniquet. To stop bleeding on extremity wounds, a tourniquet should be your go-to tool.
