DictionarySeewaveformbiphasic waveform
biphasic waveform An atypical 2-step—rather than single curve—pattern of clot formation, which is typical of disseminated intravascular coagulation (DIC), and detected by dynamic waveform analysis of changes in light transmission or absorption (LT/A), which occurs with coagulation. The biphasic waveform and gradient of the initial slope of the waveform correlate with the DIC’s severity or progression of clinical conditions.biphasic waveformA waveform used by some defibrillators that discharges energy in two phases (first positive, then negative). The shock applied by a biphasic defibrillator uses 30-40% less peak current at the same applied energy level than a monophasic defibrillator and is both less injurious to the heart and more likely to terminate ventricular fibrillation.
