Initiating Chain of Survival

Early initiation of BLS has been shown to increase the probability of survival for a person dealing with cardiac arrest. To increase the odds of surviving a cardiac event, the rescuer should follow the steps in the Adult Chain of Survival (Figure 1).

Emergencies in children and infants are not usually caused by the heart. Children and infants most often have breathing problems that trigger cardiac arrest. The first and most important step of the Pediatric Chain of Survival is prevention (Figure 2).
