Methods and systems for diagnosing disorders, including, for example, disordered breathing, involve sensing one or more of a blood chemistry parameter and/or an expired gas parameter, such as expired respiratory gas concentration, blood gas concentration, and blood pH. Diagnosis of the disorder may be performed by a medical device, such as a respiratory therapy device or a cardiac therapy device, based on implantably detected blood gas/pH concentration/level or externally detected expired respiratory gas concentration. Cardiac and respiratory therapies for addressing the disorder may be adjusted based on the detected parameters.

What is claimed is: 1. A method of providing disordered breathing therapy for a patient whose respiration cycle includes inspiration and expiration intervals, comprising:providing a patient-external respiratory therapy and a patient-internal cardiac therapy to a patient, the respiratory therapy being adapted to treat disordered breathing;measuring an expired respiratory gas concentration of an expired respiratory gas sample acquired at the end of an expiration interval of the patient as determined by a timing element, the measured expired respiratory gas concentration representative of blood gas concentration;determining one or more parameters influenced by disordered breathing, the one or more parameters comprising at least the expired respiratory gas concentration;providing one or more parameter thresholds comprising at least an expired respiratory gas threshold; andadjusting the respiratory therapy and the cardiac therapy based on the one or more parameters and the one or more parameter thresholds.
