CPR FACTS
AND STATISTICS
Approximately
95 percent of sudden cardiac arrest victims die before reaching
the hospital. About 75 percent to 80 percent of those out-of-hospital
cardiac arrests happen at home. Being trained to perform cardiopulmonary
resuscitation (CPR) can mean the difference between life and death
for a loved one.
Death from sudden cardiac arrest
is not inevitable. If more people knew CPR, more lives could be
saved. 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.
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.
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.
