The<unk>  refers to a series of actions that, properly executed, reduce the mortality associated with sudden cardiac arrest. Like any<unk> , the<unk>  is only as strong as its weakest link. The six interdependent links in the<unk>  are early recognition of sudden cardiac arrest and access to emergency medical care, early CPR, early defibrillation, early advanced cardiac life support, and physical and emotional recovery. The first three links in the<unk>  can be performed by lay bystanders, while the second three links are designated to medical professionals. Currently, between 70-90% of cardiac arrest victims die before they reach the hospital. However, a cardiac arrest does not have to be lethal if bystanders can take the right steps immediately.
