"Those MASH units are the predecessors of our modern-day trauma centers. The doctors in those units were saving people who would have died in World War II," Krentz said. "Then they came home and they saw that people were dying in the streets of essentially the same kinds of injuries."

Their experiences produced the concept of paramedics and nurses trained for critical on-the-scene treatment and constantly improving transportation times between injury and hospital, he said. Time is always the enemy because patients in or near shock can die if not treated within "the golden hour" after the injury.
