One of the requirements for completing my education as a paramedic was to shadow the Emergency Room for a few days. I can still remember the weird excitement that I felt on that day. It was almost like going to a car race because you expect to see some crashes. Hours passed by and the ER was just dead (no pun intended). With just about an hour left on my shadowing session, all of a sudden you can see that something is about to happen. The energy in the room changed, and you can see that the ER medical staffs have switched into high alert.
