体外除颤器放电能量精确控制方法研究

Study on Accurately Controlling Discharge Energy Method Used in External Defibrillator

该文提出了一种除颤器放电能量精确控制方法。从基于经胸阻抗的储能电容充电目标电压计算,以及充电电压、放电脉冲宽度的精确控制方面分别进行电路设计与编程。实际测试结果显示该方法有效,适用于各类体外除颤器。

This paper introduces a new method which controls discharge energy accurately. It is achieved by calculating target voltage based on transthoracic impedance and accurately controlling charging voltage and discharge pulse width. A new defibrillator is designed and programmed using this method. The test results show that this method is valid and applicable to all kinds of external defibrillators
