Today’s Hands-Only CPR, as recommended by the American Heart Association, is so simple, anyone can do it. Lock hands, apply where the rib cage meets in the middle, and press to the beat of the BeeGees Stayin’ Alive—100 compressions per minute—to help buy time until the medics arrive. And today’s Automated External Defibrillators, or AEDs, are so easy to use, even sixth-grade students have been known to successfully apply them with no prior instruction.

The voice commands issued by the machines walk you through each step, and the device determines whether or not a shock is advised; therefore, you cannot hurt someone by applying an AED and turning it on. These two life-saving measures are nearly foolproof– yet together, they are the critical difference between life and death.
