Abstract:
A defibrillator for delivering a multi-phasic waveform to a patient through a first electrode and a second electrode, comprising:a capacitor having a first terminal and having a second terminal, with the capacitor to store charge used for delivery of the multi-phasic waveform to the patient;a first sensor configured for measuring a first parameter related to the energy supplied to the patient by 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 controller arranged to receive the first parameter from the sensor and configured to perform an operation, using the first parameter, for actuating the connecting mechanism to decouple the capacitor from the first electrode and the second electrode; anda power supply configured for charging the capacitor to an initial voltage determined by the controller.
