  • Diagnosing hypoxia by monitoring changes in oxygen saturation
    Patent number: 8352006
    Abstract: Hypoxia is diagnosed through measurements of oxygen saturation. Some examples of hypoxia conditions that may be diagnosed include peripheral vascular disease, multiple organ dysfunction syndrome, ischemia, hypotension, and arteriosclerosis. In a specific implementation, a hypoxia condition is diagnosed based on changes in oxygen saturation in tissue. Ischemia is induced, and then measurements of changes in oxygen saturation in tissue are made. Based on changes in oxygen saturation, a diagnosis is provided of whether a patient has or does not have a hypoxia condition.

  • Diagnosis of peripheral vascular disease using oxygen saturation
    Patent number: 7247142
    Abstract: Techniques for diagnosing peripheral vascular disease using oxygen saturation are provided. Changes in oxygen saturation in tissue during recovery from induced ischemia are measured. The changes are then utilized to diagnose whether a patient has peripheral vascular disease.
