In addition to the improved defibrillation rates of
individual biphasic shocks or shock sequences, it is noted that
all patients who received treatment with 150-J biphasic
shocks were eventually defibrillated during the resuscitation
attempt and without resort to backup manual defibrillators,
which was not true for the higher-energy monophasic waveforms.
Dynamic control of waveform parameters via impedance
compensation with a 150-J biphasic shock provides
consistently high defibrillation rates without the need for
escalating energies. This finding is key to encouraging the
further evolution of small, low cost, and widely available
AED technology with dynamic waveform control techniques.
