Abstract:
1. A system, comprising: one or more neurostimulators adapted for disposition near nervous or muscular tissue involved with respiration; a control unit interfaced to the neurostimulator; one or more respiratory sensors interfaced to the control unit for detecting respiratory activity; a cardiac output sensor interfaced to the control unit for measuring cardiac output; wherein the control unit is programmed to characterize the detected respiratory activity as hypoventilation and hyperventilation and predict the onset of pathological periodic breathing from a decrease in measured cardiac output and initiate delivery of compensatory respiratory neurostimulation in response thereto that comprises excitatory stimulation of the diaphragm and/or phrenic nerve in order to augment respiratory drive during hypoventilation and inhibitory stimulation to the diaphragm and/or phrenic nerve in order to diminish respiration during hyperventilation.
