Star Biphasic Waveform
The waveform generated by the AED is a Biphasic Truncated Exponential
waveform that is compliant with ANSI/AAMI DF2 and DF39. 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.
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.
