IMPORTANT NOTE:
It is important to understand that survival rates for sudden cardiac arrest
are directly related to how soon victims receive treatment. For every
minute of delay, the chance of survival declines by 7% to 10%.
Defibrillation cannot assure survival. In some victims, the underlying problem
causing the cardiac arrest is simply not survivable despite any available care.
