In this unforgettable, dramatic account of one man's experience as an EMT, Peter Canning relives the nerve-racking seconds that can mean the difference between a patient's death and survival, as Canning struggles to make the right call, dispense the right medication, or keep a patient's heart beating long enough to reach the hospital. As Canning tells his graphic, gripping war stories-of the lives he saved and lost; of the fear, the nightmares, and the constant adrenaline-pumping thrill of action-we come away with an unforgettable portrait of what it means to be a hero.
