FEMA and other groups are pushing for more public access to and training with tourniquets because recent studies show that trained civilians can increase the chance of surviving a major trauma a huge 600%. Austere medicine instructors put together this free one-page class on how to use a tourniquet. I learned a lot from it — feels like the kind of thing that's worth the 15-minute investment. It covers what you'd learn in a local course and busts many of the myths. For example, it is no longer the case that TQs are a last resort, and they very rarely result in amputation or nerve damage.
