-
Effective bystander CPR, provider immediately after cardiac arrest, can double a victim’s chance of survival.
-
CPR helps maintain vital blood flow to the heart and brain and increases the amount of time that an electric shock from a defibrillator can be effective.
-
Approximately 95 percent of sudden cardiac arrest victims die before reaching the hospital.
-
Death from sudden cardiac arrest is not inevitable. If more people know CPR, more lives could be saved.
-
Brain death starts to occur four to six minutes after someone experiences cardiac arrest if no CPR and defibrillation occurs during that time.
-
If bystander CPR is not provided, a sudden cardiac arrest victim’s chances of survival fall 7 percent to 10 percent for every minute of delay until defibrillation. Few attempts at resuscitation are successful if CPR and defibrillation are not provided within minutes of collapse.
-
Coronary heart disease accounts for about 446,000 of the over 864,000 adults who die each year as a result of cardiovascular disease.
-
There are 294,851 emergency medical services-treated out-of-hospital cardiac arrests annually in the United States.
-
There are about 318,000 coronary heart disease deaths within one hour of symptom onset each year in the United States.
-
Sudden cardiac arrest is most often caused by an abnormal heart rhythm called ventricular fibrillation (VF). Cardiac arrest can also occur after the onset of a heart attack or as a result of electrocution or near-drowning.
-
When sudden cardiac arrest occurs, the victim collapses, becomes unresponsive to gentle shaking, stops normal breathing and after two rescue breaths, still isn’t breathing normally, coughing or moving.
