Abstract:
An energy adjusting circuit for use with a biphasic defibrillator, the defibrillator having an output with a circuit path for applying defibrillation pulse energy to a patient, the energy adjusting circuit comprising:an energy absorbing component for absorbing energy while the defibrillator is applying defibrillation pulse energy to the patient, the energy absorbing component when coupled in the circuit path of the output of the defibrillator comprising: a first energy absorbing element coupled between a first output of the defibrillator and a first circuit node; a second energy absorbing element coupled between a second output of the defibrillator and a second circuit node; and a third energy absorbing element coupled between the first and second circuit nodes; and a coupling component for coupling the energy absorbing component in the circuit path of the output of the defibrillator, the energy absorbing component when coupled in the circuit path of the output of the defibrillator absorbing a majority of the energy from the defibrillator while the defibrillator is applying defibrillation pulse energy to the patient.
