سوال جناب آقای دکتر امینی در مورنینگ در رابطه با مقایسه شوک monophasic و biphasic
Modern defibrillators are classified according to 2 types of waveforms: monophasic and biphasic.
Biphasic waveforms are safe and have equivalent or higher efficacy for termination of VF when compared with monophasic waveforms. In the absence of biphasic defibrillators, monophasic defibrillators are acceptable (Class IIb, LOE B). Different biphasic waveforms have not been compared in humans with regard to efficacy. Therefore, for biphasic defibrillators, providers should use the manufacturer’s recommended energy dose (120 to 200 J) (Class I, LOE B). If the manufacturer’s recommended dose is not known, defibrillation at the maximal dose may be considered (Class IIb, LOE C).
