A person’s chance of survival decreases by 10% with each passing minute if no CPR is performed.
Immediate CPR doubles or triples survival rates, and adding early defibrillation can increase survival to as high as 75% when performed within 3–5 minutes of collapse.
Remember three steps: call 911, push hard and fast in the center of the chest, get and use an AED (Automated External Defibrillator.)
