1. A medical device comprising:

  • a therapy delivery module configured to deliver a therapy based on a therapy delivery control parameter;

    an optical sensor for sensing a signal of light attenuated by a localized volume of a blood-perfused body tissue;

    a processor configured to;

    compute a tissue oxygenation measurement of an availability of oxygen at the localized tissue volume from the optical sensor signal during the therapy being delivered based on the therapy delivery control parameter,detect a decrease in tissue oxygenation by comparing the tissue oxygenation measurement to a threshold; and

    determine an adjusted therapy delivery control parameter in response to the decrease in tissue oxygenation tissue oxygenation.
