What do you need for a person who is unconscious?

it depends if they have just fainted or if they are going to be out for a while, it also depends on the situation. If the person faints you should rub their hands and arms and try to get circulation running. also they should be on a relatively flat surface and after they wake up, give them some food. Nothing too heavy, maybe something like crackers, and also something to drink. Something that has suger in it so that their glucose levels will stabilize.
