Abstract
The present invention provides a system for assessing the severity and stage of PAD including at least one sensor that measures skin perfusion pressure; a knowledge base that provides data on lower extremity angiosomes; and a processing device in operable communication with the sensor and the knowledge base, the processing device that outputs a visual representation of at least one of the lower extremity angiosomes that guides the sensor in the mapping of a testing site relative to a target vessel where the skin perfusion pressure measurement will be taken.
