ABSTRACT:
Techniques are provided for controlling therapy delivered in response to Cheyne-Stokes Respiration (CSR) or other forms of periodic breathing in an effort to reduce the likelihood of unnecessary therapy directed toward preventing sleep interruption. Following each burst of respiration during CSR, a prediction is made as to whether the amount of respiration achieved during the burst will be sufficient to sustain the patient through a period of apnea until the next respiration burst. If not, aggressive therapy, such as aggressive diaphragmatic pacing, is delivered to improve respiration and prevent the imminent sleep interruption. If, however, the amount of respiration achieved during the burst appears to be sufficient to sustain the patient until the next respiration burst, then relatively mild therapy is instead delivered. Preferably, the prediction is made by comparing respiration achieved during a CSR respiration burst against the minimal respiration demands of the patient, evaluated based on respiration occurring shortly after the onset of sleep.
