Study on Accurately Controlling Discharge Energy Method Used in External Defibrillator / 中国医疗器械杂志

ABSTRACT

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.
