Abstract
A system and method are presented that electrically stimulates the phrenic nerve whereby said stimulation results in muscle activation of the diaphragm as observed by a measurement of work or power of breathing associated with the inspiratory portion of a stimulated breath.
Claims8
A lead system comprising:
- a first lead having a housing containing at least two pacing electrodes spaced apart in a linear arrangement and respectively connected to connector terminals that are spaced apart from one another;
- an identifying resistor connected in a current path that extends between and connects further connector terminals and configured and arranged to provide an indication of a type of the first lead;
- and
- a controller circuit in separate electrical communication with each of the pacing electrodes and the identifying resistor, the controller circuit being configured and arranged with the at least two pacing electrodes and the identifying resistor to provoke motion of a patent's diaphragm during inspiration by providing an electrical stimulus to the patient's phrenic nerve in response to a resistance indicated by the identifying resistor and diaphragm work exerted by the patient.
