Abstract

An electrotherapy device including at least one sensor operable to sense at least one physiological parameter of a patient. A controller is operably connected to the at least one sensor operable to receive signals from the at least one sensor corresponding to the at least one physiological parameter. Memory is operable to store computer-programming code executed by the controller. The programming code includes decision-making criteria operable to adapt a patient treatment in response changes to the detected at least one physiological parameter. At least one pair of electrodes is operably connected to the controller and operable to administer the treatment to the patient.
