Read the scenario below. You are helping your brother Andrew with some home renovations when he bangs his head hard on a low beam and falls to the ground. He is unresponsive and bleeding from the spot where he struck his head. When you call 9-1-1 from your cell phone, the caller tells you an ambulance is on the way and instructs you to take steps to control the bleeding and monitor Jim's breathing. "Why watch his breathing?" you wonder since he injured his head, not his chest.
