Introduction
About the Defibrillator
The defibrillator is a portable, battery-powered therapeutic device that analyzes
the electrocardiographic (ECG) signal of a patient, interprets the indications,
advises the operator, and delivers defibrillation therapy. If the defibrillator detects
a shockable cardiac arrhythmia, it either automatically delivers a brief, high-
energy pulse of electricity to the heart of the patient or it prompts the user to
press the
SHOCK
button, depending on your model. The defibrillator delivers
energy through self-adhesive, disposable defibrillation electrodes. Internal
circuitry continuously measures the impedance between the electrodes and
allows defibrillation only when the defibrillation electrodes are attached to the
patient. Advanced arrhythmia analysis controls the critical shock/no-shock
decisions.
Main Components
The common subassemblies of the defibrillator are two, double-sided, surface-
mounted, printed circuit boards (PCBs); Readiness Display (an abbreviated
status display); a CHARGE-PAK battery charger; a QUIK-COMBO
™
patient
connector; wiring; and hardware.
