• When a bystander performs CPR, the victim's chance of surviving a sudden cardiac arrest is tripled.

• About two-thirds of deaths from heart attack occur before the victim reaches the hospital. Many of these deaths can be prevented if the victims get prompt help from someone trained in CPR. The life of the victim can be sustained until professionals are able to take over. 

• Without prompt bystander CPR, successful resuscitation of the out-of-hospital cardiac arrest victim is unlikely, despite the availability of a well-trained paramedical team with a rapid response time.

• CPR keeps a heart quivering. Victims are more often found still in “V-fib” by medics when a bystander performs CPR.

• Strangers will come to the rescue. Victims are four times likely to get bystander CPR outside the home than inside.

• In cases of cardiac arrest, the first six minutes are crucial and emergency crews often cannot get to a victim in time.
