Hands-Only™ CPR is CPR without mouth-to-mouth breaths. It is recommended for use by bystanders who see a teen or adult who suddenly collapse in an “out-of-hospital” setting (such as at home, at work or in a park). It consists of two easy steps: 
1. Call 9-1-1 (or send someone to do that) 
2. Push hard and fast in the center of the chest to the beat of Staying Alive!
