Physical Description and Features Page 1 of 7
Main Components The common subassemblies of the LIFEPAK 500 AED are a double-sided,
surface-mount Main printed circuit board (PCB), a two-line, 20-character, dot
matrix Liquid Crystal Display (LCD), a battery, a QUIK-COMBO
™ patient
connector serial port, and associated labels, wiring, and hardware.
Monophasic and
Biphasic Versions
There are two major models of the LIFEPAK 500 AED, differing in the
defibrillation pulse they generate. The LIFEPAK 500 Monophasic AED uses an
Energy Storage Capacitor and a wave shaping inductor to deliver a monophasic
(Edmark) defibrillation pulse. The LIFEPAK 500 Biphasic AED uses different
high-voltage wave shaping components to deliver a biphasic truncated
exponential (BTE) defibrillation pulse.
