A method of stimulating a diaphragm to provoke motion of the diaphragm of a patient during inspiration comprising:
- a. stimulating the phrenic nerve with a stimulation signal at a set level during a single selected breath of the patient;
- b. obtaining a measurement of the diaphragm work exerted by the patient for an inspiratory breath cycle of a selected breath of the patient;
- and
- c. modifying the stimulation signal in response to the actual value of the measurement of the diaphragm work being outside of a selected range of a value of diaphragm work exerted by the patient.
