    • A defibrillator having a pair of electrodes for delivering a defibrillation shock and a method thereof is provided. The defibrillator includes an energy-source circuit that may be discharged through electrodes on a patient to provide a biphasic voltage or current pulse. The energy-source-storage circuit is coupled across a bridge switch for delivering a defibrillation pulse to the patient through a pair of electrodes. A controller operates to control the entire defibrillation process and detects shockable rhythms from the patient via an ECG front end. The controller determines the source of the defibrillator to match the selected mode, which is inputted by connecting coded accessories, such as internal paddles, adult electrodes, or pediatric external electrodes to deliver appropriate defibrillation shocks. Other types of patient-dependent parameters are also employed to achieve the impedance compensation.
    • 提供了具有用于输送除颤电击的一对电极的除颤器及其方法。 除颤器包括能够通过患者电极放电以提供双相电压或电流脉冲的能量源电路。 能量源存储电路跨桥式开关耦合,用于通过一对电极向病人传递除颤脉冲。 控制器操作以控制整个除颤过程,并通过ECG前端检测患者的可震荡节律。 控制器确定除颤器的源与所选择的模式相匹配,该模式通过连接诸如内部桨叶,成人电极或儿科外部电极的编码附件输入,以输送适当的除颤电击。 还采用其他类型的患者依赖参数来实现阻抗补偿。
