Abstract
A means for treating breathing disorders by stimulating respiratory muscles or nerves to entrain respiratory systems while leaving respiratory drive intact. Embodiments of the invention employ frequency analysis to determine if appropriate stimulation energy is being applied.
Claims20
A system for treating disordered breathing comprising:
- an electrode lead to be disposed intravenously proximate a phrenic nerve of a patient, the electrode lead including one or more electrodes;
- a respiration sensor to sense a signal representative of respiration of the patient;
- an electrical pulse generator to provide, via the electrode lead, electrical stimulation signals to the phrenic nerve or diaphragm of the patient at a predetermined signal frequency, the electrical stimulation signals comprising a pulse train including a series of individual pulses;
- and
- a comparator to compare a spectrum of the sensed respiration signals corresponding to unstimulated breathing to a spectrum of the sensed respiration signals corresponding to stimulated breathing to determine a value indicative of capture.
