I would add some information about tourniquets also since someone mentioned it. Tqs work by compressing a vein or artery in between muscle, skin, tissue, etc and a bone to create a pinching affect. Consider placing a tq 2-3" away from joints and only over large, strong bones. In this situation, the tq should be placed 2-3" below the elbow. The radial and ulna bones of our wrist and forearm are thinner and less supported close to the hand. A heavy handed tq placed over the forearm or wrist risks a bone fracture.

Improvised tqs can be made from readily available items. Be certain to use something between 1-2" wide as the main item wrapped around the limb. I once saw someone's life saved by wrapping thin electrical wire around a severed ankle. While that soldier survived, he had alot of nerve and vessel damage that couldn't be repaired. Surgeons had to cut the limb back enough to find healthy, viable tissue and vasulature.

Thanks, Dinny
