Powerheart® AED G3 Elite 9790A and 9790E
Attenuated energy values with Cardiac Science
pediatric electrodes and STAR® biphasic waveform
The waveform generated by the AED is a Biphasic Truncated
Exponential waveform. The following is a graph of the waveform
voltage as a function of time when the AED is connected to a 50
Ohm resistive load using pediatric pads.
The Biphasic Truncated Exponential (BTE) waveform uses variable
energy. The actual energy delivered will vary with the patient’s
impedance and the device will deliver a shock when impedance
is between 25-180 Ohms. Energy will be delivered at three
different levels referred to as ultra-low variable energy, low
variable energy, and high variable energy as shown in the
waveform tables on the following pages.
