A method and system for treating an individual experiencing cardiac arrest using an automatic external defibrillator (AED) includes placing a first and a second electrode of the AED in electrical communication with an exterior surface of the individual. A need to apply a high voltage defibrillation signal to the individual is automatically determined. The method also includes automatically causing the AED to apply a medium voltage therapy (MVT) signal through the first and the second electrodes to the individual. The MVT signal is applied to induce a hemodynamic effect in the individual. Alternatively, or additionally, the MVT signal is applied to induce a respiratory effect in the individual. Optionally, the MVT signal is applied before determining the need to apply the defibrillation signal.
