Five months ago Stafford Eades collapsed at his granddaughter's birthday party at a park in Perth. But the quick thinking and actions of family and strangers saved his life.

Each year in Australia, about 26,000 people experience a sudden cardiac arrest out-of-hospital. Only 1 in 10 survive, but if a bystander can perform CPR immediately it can triple a patient's chance of survival.  Using a defibrillator within the first minute of sudden cardiac arrest, can potentially bring the chance of survival rate up to 90%.
