The terms listed in this Glossary are defined in the context of the Philips
HeartStart OnSite Defibrillator and its use.
AED Automated external defibrillator (a semi-automatic defibrillator).
AED mode The standard treatment mode for the HeartStart OnSite Defibrillator. It provides
voice instructions guiding the rescuer through applying the adhesive pads, waiting
for rhythm analysis, and delivering a shock if needed.
analysis See “SMART analysis.”
arrhythmia An unhealthy, often irregular, beating of the heart.
artifact Electrical “noise” caused by sources such as muscle movements, CPR, patient
transport, or static electricity that may interfere with rhythm analysis.
battery The sealed lithium manganese dioxide battery used to power the HeartStart
OnSite Defibrillator. It is provided in a pack that fits into a compartment on the
back of the OnSite.
Caution light A triangular light on the front of the HeartStart OnSite Defibrillator that flashes
during rhythm analysis and is on solid when a shock is advised, as a reminder not
to touch the patient.
configuration The settings for all operating options of the HeartStart OnSite Defibrillator,
including treatment protocol. The factory default configuration can be modified by
authorized personnel using HeartStart Event Review software.
CPR Cardiopulmonary resuscitation. A technique for providing artificial respiration and
heart compressions.
CPR Coaching Basic verbal instructions for performing cardiopulmonary resuscitation, including
hand placement, rescue breathing, compression depth and timing, provided by the
OnSite when the flashing blue i-button is pressed during the first 30 seconds of a
patient care pause.
defibrillation Termination of cardiac fibrillation by applying electrical energy.
ECG Electrocardiogram, a record of the electrical rhythm of the heart as detected
through defibrillation pads.
fibrillation A disturbance of the normal heart rhythm that results in chaotic, disorganized
activity that cannot effectively pump blood. Ventricular fibrillation (fibrillation in the
lower chambers of the heart) is associated with sudden cardiac arrest.
