Abstract :
In order to make the actual defibrillation energy approximate to target defibrillation energy in automated external defibrillator, an energy compensation method is proposed in this paper. The transthoracic impedance is measured first, and then the charging voltage of energy storage capacitor is determined based on this impedance and target defibrillation energy. The system includes three parts, stimulation module, detection module and determination module. The system has been tested by standard resistor and animal experiments. The standard resistor experiments confirm that the system can work well, while the animal experiments validate the accuracy of the transthoracic impedance measurement and the effect of energy compensation. The effect of energy compensation based on our transthoracic impedance measurement is remarkable.
