Shock

Shock is a dangerous condition that comes with almost all injuries. You should always be on the watch for it, or, better, take for granted that it is there and do what you can to prevent it from becoming serious.

The patient gets faint, his face pale. He may become unconscious. Don't let that happen. Lay him down immediately, flat on his back, with head to one side. Keep him warm by putting blankets or coats around him.
