YOU CAN MAKE A DIFFERENCE
In 1990, the
American Heart Association developed the Chain of Survival.
This protocol addresses the fact that most Sudden Cardiac Arrest (SCA)
episodes occur outside of a hospital, with death occurring within
minutes of onset. For the Chain to be effective, quick
execution of each and every link is critical. With each minute
that passes, the likelihood of survival decreases 7-10%.

When
each link in the chain works successfully, the chance of surviving
SCA increases greatly.
Since more than 70% of SCA cases occur at home, and another 10% to
15% occur at work, trained EMS personnel are unlikely to be at the
scene at onset. Therefore, trained lay responders with quick
access to defibrillation units can be a vital asset when SCA
strikes. In certain environments, where the Chain is strong
and when defibrillation occurs within the first few minutes of
cardiac arrest, survival rates can approach 80% to 100%.
People who survive sudden cardiac arrest have an excellent
prognosis: 83% survive for at least one year, and 57% survive for
five years or longer. In fact, when analyzed by age group,
survival rates for SCA survivors are comparable to survival rates of
people who have never had an event. Clearly, early
intervention can offer years of productivity and fulfillment to
victims of SCA.
