Abstract:
Objective To investigate the techniques of electrical defibrillation and their application to cardiopulmonary re-suscitation(CPR).Methods On the basis of reviewing the definition of electrical defibrillation,the main defibrillation tech-niques and their developments were introduced,as well as the selection of shock energy.The role that defibrillation played during CPR was defined according to the consensus.Results As an unfashionable technique,monophasic waveforms was inclined to be replaced by present biphasic waveform including biphasic truncated exponential(BTE) waveform and recti-linear biphasic waveform(RBW).The selected shock energy varied with the waveform that a defibrillator made use of,i.e.a monophasic defibrillator required a higher energy level as usual,whereas a biphasic one did not.It was deemed that biphasic technique presented an excellence in less damage to heart in addition to higher rate of successful defibrillation.In the critical care for sudden cardiac arrest with a shockable rhythm,the protocol of "1 shock + 5 cycles of CPR" should be recommended.Conclusion Electrical defibrillation techniques consist mainly of monophasic waveform and biphasic wave-form,between which the latter gains an advantage over the former.On the grounds of modern emergency medicine,defib-rillation has to be performed in combination with CPR.
