Disclosed herein is a method for obtaining a value of at least one vasodilation parameter representing the cutaneous local thermal hyperemia response of a subject. The temperature of a sampling site is raised from a first temperature to a second temperature and maintained for an initial heating period, and an initial maximum red blood cell flux (RBCF) of the sampling site and a mean arterial pressure of the subject is obtained. An initial maximum cutaneous vascular conductance (CVCI, max) is calculated by dividing the initial maximum RBCF by the mean arterial pressure. The CVCI, max or at least one other parameter derived therefrom is used as the vasodilation parameter.在此揭示一種用以取得一個體之至少一血管擴張參數值的方法,此參數值可表示所述個體之皮膚局部熱充血反應。在一初始加熱期間內,將一採樣部位之溫度由第一溫度加熱至第二溫度,並取得所述個體之採樣部位的一初始紅血球通量峰值及一平均動脈壓。一初始皮膚血管傳導峰值係以所述初始紅血球通量峰值除以平均動脈壓而得。以初始皮膚血管傳導峰值或由其所衍生的至少一其他參數作為所述血管擴張參數值。100‧‧‧雷射都卜勒設備110‧‧‧使用者介面120‧‧‧雷射都卜勒偵測器130‧‧‧加熱單元140‧‧‧控制器150‧‧‧運算單元160‧‧‧資料庫170‧‧‧比較單元180‧‧‧分析單元190‧‧‧儲存單元200‧‧‧電腦
