1. An implantable neurostimulation system for delivering a respiratory therapy to a subject, comprising:
- a neurostimulator adapted to deliver a neurostimulation signal to the subject, the neurostimulator comprising a microprocessor programmed to;
titrate a stimulation setting of the neurostimulator while the subject is awake by delivering a first set of stimulation pulses at a plurality of first stimulation setting values between a lower limit defined by a capture threshold corresponding to a beneficial effect of the respiratory therapy and a first upper limit defined by a comfort threshold corresponding to a negative sensation experienced by the subject; and
subsequently, when the subject is asleep, repeat the step of titrating the stimulation setting of the neurostimulator by delivering a second set of stimulation pulses at a plurality of second stimulation setting values, wherein one or more of the plurality of second stimulation setting values is different than one or more of the plurality of first stimulation setting values and the plurality of second stimulation setting values are between the lower limit defined by the capture threshold and a second upper limit defined by a threshold at which the patient is expected to at least partially arouse from sleep.
