1. A neural stimulation system, comprising:
- a therapy output device adapted to deliver one or more therapies, the therapy output device including a non-respiratory stimulation output circuit adapted to deliver a neural stimulation therapy treating a non-respiratory disorder;
a therapy delivery controller coupled to the therapy output device, the therapy delivery controller adapted to control the delivery of the one or more therapies and including a non-respiratory stimulation delivery controller adapted to control the delivery of the neural stimulation therapy;
a respiratory signal input adapted to receive a respiratory signal;
a respiratory disorder detector coupled to the respiratory signal input, the respiratory disorder including an apnea detector adapted to detect apnea using the respiratory signal; and
a therapy adjustment module coupled to the respiratory disorder detector and the therapy delivery controller, the therapy adjustment module adapted to adjust the delivery of at least one of the one or more therapies in response to the detection of apnea.

Abstract
A neural stimulation system controls the delivery of neural stimulation using a respiratory signal as a therapy feedback input. The respiratory signal is used to increase the effectiveness of the neural stimulation, such as vagal nerve stimulation, while decreasing potentially adverse side effects in respiratory functions. In one embodiment, the neural stimulation system detects apnea and, in response, adjusts the delivery of the neural stimulation pulses and/or delivers a respiratory therapy treating the detected apnea.
