Myth № 7. The most important thing is to make a tourniquet, and it doesn’t matter how.
It may be true that more people died because of bad tourniquets, than because of losing blood. The most common mistake is putting the tourniquet right on the skin. You should never do this because this may damage the skin severely. The second mistake is putting a tourniquet on for a very long time. At least once an hour, or even better, every 20 minutes you should loosen the tourniquet to let the blood flow to the limb. If you don’t do this, the limb may have to be amputated.
