1. A medical device for monitoring delivery of a therapy, comprising:

  • a sensor sensing an optical sensor signal corresponding to light attenuation by a volume of body tissue of a patient;

    a therapy delivery module to deliver the therapy; and

    a processor configured to compute a first tissue oxygenation measurement from the optical sensor signal prior to initiating delivery of the therapy, compute a second tissue oxygenation measurement from the optical sensor signal subsequent to initiating delivery of the therapy, compare the first and the second tissue oxygenation measurements, and determine whether the delivered therapy was successful in response to the first tissue oxygenation measurement and the second tissue oxygenation measurement.
