I understand that there is a difference between physical and emotional shock. What I would hate to see is some lay person ASSUMING that a victim is in emotional shock. I would bet that symptoms of both kinds can mimic the other. I'm sure that "invisible" physical trauma does exist, and lay people have no business making a diagnosis between the two kinds. Just because the person is breathing and blood isn't pouring out is no indication that the problem is "only" emotional trauma.
The victim should be kept quiet and warm, and medical assistance should be called ASAP. No judgments as to cause really need to be made. Let medical personnel do that.
