Waveform Biphasic truncated exponential.
Waveform parameters are automatically adjusted as a function of patient
defibrillation impedance.
In the diagram at left, A is the duration of phase 1 and B is the duration of phase 2
of the waveform, C is the interphase delay, V
p
is the peak voltage, and V
f
the final
voltage.
The H
EARTSTREAM FR2 delivers shocks to load impedances from 25 to 180 ohms.
The duration of each phase of the waveform is dynamically adjusted based on
delivered charge, in order to compensate for patient impedance variations, as
shown in the following examples:
Load Phase 1 Phase 2 Delivered
Resistance (ohms) Duration (ms) Duration (ms) Energy (J)
25 2.8 2.8 140
50 4.09 4.09 150
100 9.0 6.0 157
125 12.0 8.0 161
150 12.0 8.0 157
Energy 150 J nominal into a 50 ohm load.
Charge Control Controlled by Patient Analysis System for semi-automatic operation. Can be
programmed for manual initiation using Advanced Mode of the M3860A.
