Abstract
Systems for controlling or aiding patient therapy are provided. The systems may include a tissue oxygenation measurement device and a therapy delivery apparatus that is controllable to assist in attaining a target tissue oxygenation level or range, whereby patient health is improved by optimizing delivery of therapy based on measured tissue oxygenation. The therapy delivery apparatus may include, for example, a drug delivery apparatus, a ventilating apparatus, a fluid delivery apparatus and/or a chest compression delivery apparatus. The tissue oxygenation measurement device may include a probe for determining the oxygenation of tissue, for example, muscle tissue, by optically interrogating the tissue. Related methods for guiding patient therapy and exercise training are also provided.

5. A system for guiding patient therapy, the system comprising:
-
a probe for detecting in vivo tissue oxygenation in a patient; a drug delivery apparatus; and a controller coupled to the probe and the drug delivery apparatus, the controller configured to measure an oxygenation level of the patient'"'"'s tissue using the probe and the following ratio;
oxymyoglobin+oxyhemoglobin(deoxymyoglobin+deoxyhemoglobin)+(oxymyoglobin+oxyhemoglobin), and to adjust delivery of a pharmaceutical drug to the patient via the drug delivery apparatus based at least in part on said ratio, whereby the patient'"'"'s tissue oxygenation is modified toward a target level.
