Abstract
An implantable cardiac stimulation device treats apnea with either phrenic nerve stimulation pulses or cardiac stimulation pulses. The device includes an apnea detector that detects apnea of a patient, a blood oxygen saturation monitor that measures a blood oxygen saturation level of the patient responsive to detection of apnea, and a tiered therapy circuit that provides phrenic nerve stimulation pulses if the measured blood oxygen saturation level is within a first range and cardiac stimulation pulses if the measured blood oxygen saturation level is within a second range. The cardiac stimulation pulses are preferably provided in a DAO pacing mode.
