The Chain of Survival

The chain of survival is an important concept related to saving the lives of someone with SCA. There are five links.

Community has the biggest role in the first 3 links (i.e. early access to emergency care, early CPR and early defibrillation). Communities with a stronger chain of survival usually have a higher chance of survival and recovery for SCA victims. Bystander- CPR initiated before the arrival of the emergency medical service can increase the chance of survival up to 3 times among victims of SCA in comparison to those without such assistance.
