血压反馈(blood pressure feedback)把被试的血压变化呈现给其本人的方法。目的是使被试学习对自己的血压变化进行控制,从而使血压稳定在一定水平上。具体做法有动脉插管法(只适用于动物)、特尔斯基法和脉搏波速度法。特尔斯基法是把一个微音器放在肘窝处的动脉上以代替听诊器,并以可充气的袖带加以固定。当血液流过动脉时,便会振动微音器,经放大后推动扬声器发出声响.这种声音称Korotkoff声(简称Ks)。
为了使这活动更加具有羞辱性,研究人员通过耳机给予参与者消极的反馈,并全程检测参与者表现出的压力反应,如高血压。
To make the experience still more humiliating, the team provided negative feedback through headphones, all the while checking participants for indications of stress, such as high blood pressure.
根据调定点学说,设计了一种植入式芯片系统,根据血压的反馈信息,经过芯片运算处理,即时改变刺激主动脉神经(ADN)的脉冲频率,从而调控血压。
Based on the set point theory, an implanted chip system was designed to regulate the blood pressure by stimulating the aortic depressor nerve (ADN) according to the feedback of blood pressure.
