Wounded people often die not of traumas but because first aid was late. For example: at injury of an artery didn't manage to stop quickly bleeding or the victim choked lying on a back. A part of death on conscience of those who having appeared nearby, didn't know what to do. The main thing in such situation - to learn it is correctly to operate in the first seconds of detection of the victim to keep to it life before ambulance arrival. And still main in such situations - not to give in to a panic
