Introduction
Terminology
The following terms appear in this manual.
AED Automated External Defibrillator. A device that evaluates the victim’s heart
rhythm and delivers an electrical shock to the heart if a shockable rhythm is
detected.
Cardiac arrest The termination of the heart’s pumping action resulting in the lack of a
heartbeat or pulse and breathing.
CPR Cardiopulmonary resuscitation. This involves delivering rescue breathing and
chest compressions to a victim in cardiac arrest.
Defibrillation Delivery of an electrical shock to the heart for the purpose of reversing
ventricular fibrillation.
ECG Electrocardiogram. A composite picture of what is occurring electrically in the
heart.
Fibrillation Chaotic activity of the heart’s electrical system. This condition can occur in
the atria or the ventricles. When it occurs in the ventricles, they quiver in a
rapid, chaotic manner, preventing them from pumping blood to the body.
Heart attack A nonspecific term referring to the death of heart muscle resulting from
interruption of blood supply, often confused with cardiac arrest.
Impedance Resistance to the flow of electrical current through the body.
Joule The basic unit of energy delivered by a defibrillator.
LED Light emitting diodes.
Myocardial infarction The specific term for what is usually meant by heart attack; death of heart
muscle resulting from an interruption of the blood supply to that area of
myocardium.
Nonshockable rhythm A heart rhythm that is detected by the defibrillator that does not need a
shock, but may need CPR.
Victim In this manual, the person suffering from cardiac arrest.
Responder In this manual, the person giving aid to a victim in cardiac arrest. Used
interchangeably with user.
SAS Physio-Control patented Shock Advisory System ™ .
Shockable rhythm A heart rhythm that is detected by the defibrillator as requiring a shock, for
example, ventricular fibrillation.
User In this manual, the person giving aid to a victim in cardiac arrest. Used
interchangeably with responder.
Ventricular fibrillation A life-threatening chaotic heart rhythm.
Ventricular tachycardia Rapid heart rhythm originating in the ventricle.
