1. A method of controlling an implantable pulse generator for baroreflex activation, comprising:

  • applying electrical power from the pulse generator to a nerve or a receptor;

    monitoring the energy level of the pulse generator, including producing a signal representative of the energy level of the pulse generator in response to the energy level of the pulse generator reaching a first threshold energy level;

    changing the operation of the pulse generator to adjust the electrical power output of the pulse generator while maintaining adequate physiological response, comprising reducing energy consumption of the pulse generator in response to the signal representative of the energy level of the pulse generator while maintaining adequate baroreflex response; and

    monitoring the energy level of the pulse generator until the energy level reaches a second threshold level and generating a signal representative of the energy level of the pulse generator.
