8.1.6 Clinical Summary
The DDU-100 AED uses a Biphasic Truncated Exponential waveform with specifications that are
substantially equivalent to the waveform specifications of the device used in the study

below. The DDU-100 AED has not been the subject of a published clinical study.
8.1.6.1 Background
The objective of this study was to compare AEDs that delivered 150-J biphasic shocks with AEDs
that delivered high-energy (200- to 360-J) monophasic shocks.
