摘要：
A controller delivers electrical stimulation therapy to a diaphragm through the one or more electrodes, and obtains a signal indicative of a pressure within an intrathoracic cavity from a pressure measurement source. The electrical stimulation therapy is defined by stimulation parameters. The controller obtains at least one additional signal indicative of a pressure within an intrathoracic cavity by changing at least one of the stimulation parameters, and delivering an electrical stimulation therapy to the diaphragm in accordance with the changed one of the plurality of stimulation parameters. The controller repeats the process of obtaining additional signals indicative of pressure based on a changing stimulation parameter by scanning through a range of values for the changing stimulation parameter. The controller derives a measure of interest from each of the obtained signals, and selects as an optimal stimulation therapy, the electrical stimulation therapy that results in a most acceptable measure of interest.
