Cardiac Arrests: Increasing the Chances of Survival

pictograms of events during cardiac arrest

A person is most likely to survive an out-of-hospital cardiac arrest if:

  • Their cardiac arrest is either witnessed by a bystander or the victim is discovered immediately after collapsing
  • The bystander calls the emergency medical services immediately
  • The bystander delivers effective cardiopulmonary resuscitation (CPR) without delay
  • There is a defibrillator close by, which another bystander can fetch
  • The bystanders use the defibrillator without delay
