Early Recognition and Call for help

Calling 999 when necessary is the first important link in the Chain of Survival

Early CPR

Many members of the public are trained in the delivery of Cardio Pulmonary Resuscitation (CPR)
When you call 999, an Emergency Call Handler can provide CPR instructions to the caller to perform life saving skills while an Ambulance crew is responding to the call.

Early Defibrillation

Early Advanced Care

Post resuscitation care from an Ambulance crew and Specialist Cardiac Hospital care.
