It is crucial that help is sought immediately following a cardiac arrest by
CPR (cardiopulmonary resuscitation) and artificial respiration (mouth to mouth
resuscitation) provides enough circulation to temporarily keep small amounts of oxygenated
blood circulating through vital organs. This keeps the heart and brain viable until
the AED (Automated External Defibrillator) arrives.
The purpose of early defibrillation is to re-establish a normal heart rhythm.
Scientific research has shown that early defibrillation greatly increases the chance
of survival for someone in cardiac arrest.
Early Advanced Cardiac Life Support is the treatment provided by the paramedics
when they arrive.
Thirty years ago, it was discovered that if a series of events took place, in a set
sequence, a patient suffering from a heart attack stood a greater chance of survival.
These events are now known as the ' Chain of Survival'
