| 1. A method of diagnosing peripheral vascular disease by causing a body part of a patient to experience occlusion, which comprises
an ischemia phase, the method comprising:
measuring oxygen saturation in tissue of the patient during the ischemia phase;
analyzing the oxygen saturation in the tissue during the ischemia phase; and
diagnosing the patient as having peripheral vascular disease according to changes in the oxygen saturation in the tissue during
the ischemia phase.
