CPR Facts and Statistics
About 75 percent to 80 percent of all out-of-hospital cardiac arrests
happen at home,
so being trained to perform cardiopulmonary resuscitation
can mean the difference between life and death for a loved one.
Effective bystander CPR, provided 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 knew CPR, more lives could be saved.
Brain death starts to occur four to six minutes after
someone experiences cardiac arrest if no CPR and
during that time.
If bystander CPR is not provided, a sudden cardiac
chances of survival fall 7 percent to 10 percent for every
minute of delay until defibrillation. Few attempts at resuscitation
and defibrillation are not provided within minutes of collapse.
Coronary heart disease accounts for about 550,000
of the 911,000 adults who die as a result
of cardiovascular disease.
Approximately 330,000 of all annual adult
coronary heart disease deaths in the U.S.
are due to sudden
outside the hospital
setting and in hospital emergency departments.
About 900 Americans die every day due to
Sudden cardiac arrest is most often
caused by an abnormal heart rhythm
can also occur after the onset
of a heart attack or as a result of electrocution
When sudden cardiac arrest occurs,
the victim collapses, becomes
unresponsive to gentle
shaking, stops normal
after two rescue breaths,
still isn’t breathing normally,
coughing or moving.
