Cold exposure treatments including cryotherapy have been developed because of many physiological effects, one of which is the vascular hunting reaction called CIVD. In this study, CIVD was determined from the experiments where subject's right forearm was exposed to various air temperatures. The experiments were carefully designed to induce no pain during cold exposure. Three female and three male subjects participated in the experiments. The right forearm and hand of the subject were exposed to control/cold air temperatures of 30 degrees C/-10 degrees C, 15 degrees C/-15 degrees C, 40 degrees C/-20 degrees C and 25 degrees C/-35 degrees C. Blood flow in the middle finger and skin/core temperature at the middle of the forearm and back of the hand were measured simultaneously. Results showed that the exposure to -10 degrees C for 30 min may induce CIVD most effectively without pain as compared to the other given conditions.
包括冷冻疗法在内的冷暴露疗法因其多种生理效应而得以发展，其中之一就是所谓的冷诱导血管舒张（CIVD）这种血管波动反应。在本研究中，通过让受试者右前臂暴露于不同气温的实验来测定CIVD。实验经过精心设计，以确保在冷暴露期间不会引起疼痛。三名女性和三名男性受试者参与了实验。受试者的右前臂和手部被暴露于30℃/-10℃、15℃/-15℃、40℃/-20℃和25℃/-35℃的对照/冷空气温度下。同时测量中指的血流量以及前臂中部和手背的皮肤/核心温度。结果表明，与其他给定条件相比，在-10℃下暴露30分钟可能最有效地诱导CIVD且不会引起疼痛。
