When an adult suddenly collapses, trained or untrained bystanders – that means a person near the victim – should:

1) Call 911 (From a Cell Phone) or 10177 from a land line.
2) Push hard and fast in the center of the chest.

Studies of real emergencies that have occurred in homes, at work or in public locations, show that these two steps, called Hands-Only CPR, can be as effective as conventional CPR. Providing Hands-Only CPR to an adult who has collapsed from a sudden cardiac arrest can more than double that person’s chance of survival.

It’s not normal to see an adult suddenly collapse, but if you do, call 911 and push hard and fast in the center of the chest. Don’t be afraid. Your actions can only help.
