A gas therapy system involves sensing the blood gas concentration of the patient and adapting a gas therapy based on the sensed gas concentration. Disordered breathing may be detected bases on blood gas concentration, and gas or cardiac electrical therapy may be adapted to treat the detected disordered breathing. One or more of sensing the blood gas concentration, detecting disordered breathing, or adapting the therapy may be performed at least in part implantably. The gas therapy is delivered to the patient through an external respiratory device, such as a positive airway pressure device.
