Patent ID: 8914113

Claim:
A method for respiratory control using an implantable medical device, the method comprising: sensing a respiratory signal; detecting events indicative of respiratory cycles using the respiratory signal, the respiratory cycles indicative of an intrinsic respiratory rate; detecting one or more respiratory performance parameters indicative of respiratory performance from the respiratory signal, the one or more respiratory performance parameters including a minute ventilation; delivering stimulation at a stimulation rate approximately equal to the intrinsic respiratory rate for a period of time allowing the respiratory cycles to be under control of the stimulation, the delivery of the stimulation synchronized to the respiratory cycles; decreasing the stimulation rate after the period of time at a rate allowing the respiratory cycles to adapt to the stimulation rate until the stimulation rate reaches a target respiratory rate; and determining whether to inhibit the delivery of the stimulation based on whether the one or more respiratory performance parameters indicate hyperventilation and whether the one or more respiratory performance parameters indicate hypoventilation.
