Answer:
Prevention
Explanation:
The adult cardiac chain of survival refers to the chain of events in order to treat a medical emergency. The first link is the recognition of the emergency and acts in consequence. In the second place, it is imperative to know how to apply cardiopulmonary resuscitation (this procedure combines chest compression with ventilation in order to preserve brain function). Third, it is required to apply early defibrillation by using electrical shocks to regain the regular motion of the hearth. The next link is the arrival of Emergency Medical Services (EMS) personnel to providing care in the prehospital emergency setting, which continues in the hospital emergency rooms.
