KICK-START A HEART

This is as close as you'll ever come to bringing someone back from the dead.

• Place one hand on the breast-bone, put your other hand atop your first hand, lock the fingers together.

• Give 15 quick , firm chest compressions. You don't want to overdo it.

• After 15 minutes compressions, give two rescue breaths. Continue the cycle until help arrives or you collapse dramatically from exhaustion.
