Abstract:
A defibrillator for delivering a multi-phasic waveform to a patient through a first electrode and a second electrode, the defibrillator comprising:a capacitor having a first terminal and a second terminal, with the capacitor to store charge used for delivery of the multi-phasic waveform to the patient;a power supply configured for charging the capacitor;a connecting mechanism coupled between the first terminal and the second terminal of the capacitor and the first electrode and the second electrode to permit the first terminal of the capacitor to selectively couple to one of the first electrode and the second electrode and to permit the second terminal of the capacitor to selectively couple to one of the first electrode and the second electrode;a waveform measuring device for measuring an ECG waveform; anda controller coupled to the connecting mechanism and arranged to receive the ECG waveform from the waveform measuring device, with the controller configured to adjust the multi-phasic waveform based upon the ECG waveform.
