The cold test represents an essential part of the functional exploration of the vascular system performed in Raynaud's disease, but its physiological nature depends upon the use of a sufficiently large area of skin. Several measurements must be conducted simultaneously and various temperature ranges used to allow for the variable threshold of vascular reactivity to cold of different individuals. A thermal chamber is presented which enables the simultaneous performance of plethysmography, digital pressure recordings and capillaroscopy at different temperature ranges. A novel use of a laser flowmeter is also described. Peri-ungual capillaroscopy enables determination of the temperature, when capillary spasm appears and then is relieved during progressive cooling followed by reheating. This apparatus can be adapted for use of all techniques for exploration of vascular function.
冷试验是雷诺病中对血管系统进行功能探索的重要组成部分，但其生理特性取决于对足够大面积皮肤的使用。必须同时进行多项测量，并使用不同的温度范围，以适应不同个体对寒冷的血管反应阈值变化。本文介绍了一种热室，它能够在不同温度范围内同时进行体积描记法、数字压力记录和毛细血管镜检查。还描述了激光流量计的一种新用途。甲周毛细血管镜检查能够确定在逐渐冷却随后再加热过程中毛细血管痉挛出现及缓解时的温度。该装置可适用于所有血管功能探索技术。
