A method for assessing a vascular stiffness index uses an airbag to impose pressure on a limb of a subject to assess the stiffness index of a blood vessel, comprising a pressure imposing step, a pressure releasing step and a calculation step. The pressure imposing step and the pressure releasing step are used to obtain the diastolic blood pressure, systolic blood pressure and average artery blood pressure of the blood vessel. In the calculation step, the blood vessel volume variation during the blood pressure measurement can be calculated. Given the blood vessel pressure is equal to the average artery blood pressure, the vascular stiffness index is the difference of the systolic blood pressure and the diastolic blood pressure divided by the blood vessel volume variation. Accordingly, without using expensive facilities or complicated measurement and analysis, the vascular stiffness index can be measured if diastolic blood pressure, systolic blood pressure and average artery blood pressure are obtained, thereby simplifying measurement and analysis and reducing equipment cost.一種血管硬化指標之檢測方法,利用一氣囊對一受測者之肢體施壓來檢測血管的硬化程度,且包含一加壓步驟、一洩壓步驟,及一計算步驟。透過該加壓步驟及洩壓步驟獲得血管的舒張壓、收縮壓,及平均動脈血壓,並於該計算步驟中推算獲得血壓量測過程中的血管體積變化量,在血管壓力等於平均動脈血壓的狀態下,血管的硬化指標是以收縮壓與舒張壓的差異值除以血管體積變化量。藉此,不需使用昂貴的儀器或是複雜的量測及分析方式,只要獲得血管的收縮壓、舒張壓,以及血管體積變化量,就能計算出血管硬化指標,不僅容易量測分析,也能降低設備成本。3...加壓步驟4...洩壓步驟5...計算步驟
