ABSTRACT:
Peripheral vascular disease is diagnosed through measurements of oxygen saturation. In a specific implementation, peripheral vascular disease is diagnosed based on changes in oxygen saturation in tissue. Ischemia is induced, and measurements of changes in oxygen saturation in tissue are made. Based on changes in oxygen saturation during an accumulation phase, a diagnosis is provided of whether a patient has or does not have peripheral vascular disease.
