History of Defibrillator Technology – Biphasic Defibrillators Conversely, as technology continued on its ever-evolving journey of intermingling with and augmenting the limits of the human body and mind, advances in the medical field eventually paved the way for a new type of waveform technology, known as biphasic waveform defibrillation.

M Series with Rectilinear Biphasic Waveform Defibrillator Option Indications for Use and Section 5 (for Manual Defibrillation, Advisory Defibrillation and Automated Defibrillation) of this M Series Operator’s Guide are modified to add the word “BIPHASIC” to the energy display as shown below. The M Series is capable of delivering energy up to 200 Joules with external paddles or Multi-Function Pads. The initial … The biphasic waveforms delivered by these devices each have different waveform characteristics and impedance compensation schemes and, most importantly, different recommended energy levels. The optimal biphasic waveform, energy level and shock sequence (escalating energy versus fixed dose) has not been determined.
