When my son was in the neo-natal unit I saw a number of parents go completely off the deep-end over any number of minor changes to their child's condition.... To avoid this around my son, I told my wife, parents and all other visitors that you only ever had to worry if you saw a doctor or nurse running....as what may seem to be a life or death situation is in fact an everyday occurrence to somebody who works in medicine. I would imagine the same goes for EMTs / Paramedics?
