A manual defibrillator is one of those machines you see on emergency medical TV shows, when the doctor places a flat “paddle” on one side of a person ‘s chest and another across the heart from it on the other side , yells “ changing” and “clear” so that everyone takes a step back and shocks the heart with an electrical charge to get it beating again. That’s a manual one. A newer kind, an automatic external defibrillator , or AED, is smaller, computerized, reads the electric signals of the heart and determines if s shovk is needed., and administers a shock if necessary. It is designed for minimally trained persons to use if someone in a public building has a heart attack.
