Most people who experience cardiac arrest at home, work or in a public location die because they don't receive immediate CPR from someone on the scene. As a bystander, don't be afraid. Your actions can only help.
How to Give Hands-Only CPR
Hands-Only CPR is CPR without mouth-to-mouth breaths. It is recommended for use by people who see a teen or adult suddenly collapse in an “out-of-hospital” setting (such as at home, at work or in a park). It consists of two easy steps:
Call 9-1-1 (or send someone to do that).
Push hard and fast in the center of the chest to the beat of the classic disco song "Stayin' Alive." CPR can more than double a person's chances of survival, and "Stayin' Alive" has the right beat for Hands-Only CPR.
