在休息、局部加温和局部降温时测量手血流量。同时使用三种方法：水体积描记法（WP）、橡胶汞应变计体积描记法（SG）和脉冲Döppler流量计（D）。其中，水体积描记法是最敏感和准确的;应变计体积描记法更简单，但不太准确;脉冲Döppler流量计精确地测量瞬时动脉血流量，而没有静脉闭塞。
Hand blood flow was measured at rest, with local warming, and with local cooling. Three methods were simultaneously used: water plethysmography (WP), mercury-in-rubber strain gauge plethysmography (SG), and pulsed Döppler flowmetry (D). Of these, water plethysmography is the most sensitive and accurate; strain gauge plethysmography is simpler but less accurate; and pulsed Döppler flowmetry precisely measures instantaneous arterial blood flow without venous occlusion.
