What is the chain of survival? 
When someone suffers an out of hospital Cardiac arrest; if certain things happen in a certain order, their chances of survival increased. This concept is now known as the Chain of Survival. 
 
The Chain of survival is made up of four links; 
 
1. Early recognition: being able to recognise someone is in Cardiac arrest is the first step to helping them. Call 999/112 
 
2. Early CPR: by performing chest compressions you can keep their heart going until a defibrillator arrives. 
 
3. Early defibrillation: For every minute the person doesn't have a defibrillator attached to their chest, their chances of survival reduce by 10%. 
 
4. Early advanced care: This is delivered by the paramedics who arrive shortly after. If you start CPR within 2 minutes, place a defibrillator on their chest in four minutes and a paramedic arrives in 8, they have a 40% chance of survival.
