    • An external defibrillator is described which maintains the durations of phases of a multiphasic shock waveform within or below desired limits. As the duration of a waveform increases for patients of increased patient impedance, the durations of the phases of a multiphasic shock waveform also increase. Before a maximum duration limit is exceeded, the defibrillator adds another phase to the multiphasic waveform which brings the durations of the phases within the desired range or below a maximum duration limit. Both the number of shock phases and the individual phase durations can be controlled in response to measured patient impedance.
    • 描述了外部除颤器,其将多相冲击波形的相位持续时间保持在期望限度内或低于期望的极限。 随着患者阻抗增加的患者的波形持续时间增加,多相休克波形的相位持续时间也增加。 在超过最大持续时间限制之前,除颤器将另一个相位添加到多相波形,使相位持续时间在所需范围内或低于最大持续时间限制。 可以响应于测量的患者阻抗来控制冲击相数和个体相持续时间。
