  • AUTOMATED ASSESSMENT OF PERIPHERAL VASCULAR CONDITION
    Publication number: 20170215746
    Abstract: An automated assessment of a patient's peripheral vascular condition includes using a pulse oximeter to generate at least a perfusion index relative to a limb or digit of the patient. Pressure is applied to the limb or digit, and while increasing or decreasing the pressure, a change in the perfusion index is determined. The change is indicative of a cessation of blood flow or a return of blood flow in the limb or digit. A systolic blood pressure is thereafter determined based on the pressure applied at the time of cessation of blood flow or the return of blood flow in the limb or digit. Using a pulse oximeter to generate a perfusion index may include transmitting light into the limb or digit, detecting light that was transmitted into tissue in the limb or digit, and calculating the perfusion index based on the light transmitted through the tissue.
