Abstract
A defibrillator incorporates a method and device for determining the energy delivered to and electrical resistance of biological tissues. The defibrillator's method and device achieve these determinations by measuring the pre-discharge voltage on the defibrillator's capacitors which are to be discharged into the body; measuring the post-discharge voltage across the capacitors which are subsequently discharged into the biological tissues; and calculating both the energy delivered to the biological tissues and the electrical resistance of the biological tissues on the basis of the measured pre-discharge and post-discharge defibrillator capacitor voltages.
