摘要
The invention concerns a method which consists in measuring the patient's transthoracic resistance between two defibrillation electrodes applied to the patient during a defibrillation impact by using the first elementary pulse derived from chopping and modulation of the defibrillation pulse(s) to measure the patient's transthoracic resistance, the following elementary pulses being modulated so as to deliver to the patient the pre-selected or intended energy, independently of his transthoracic resistance between the defibrillation electrodes and without increasing the total duration of the series of impulses. The device consists of a user interface (1), a microcontroller (2), a high voltage generator (3), a high voltage circuit (4) and a wave form generator (5). The present invention is of interest to manufacturers of defibrillators.
