现代测量技术能够从中心和外周两个角度对心血管功能进行无创观察。心血管动力学的特点是由几个不同的频率分量，这些都存在于系统的每个站点。相应的振荡过程是相互依赖的，通过耦合，导致振幅/频率波动的特征峰。新的研究已经开始，以确定心血管振荡和一些脑电波之间的相互作用。这项工作将被审查和因果关系将讨论一个特别强调检测麻醉深度
Contemporary measurement techniques enable noninvasive observations of cardiovascular functions, both from the central and peripheral points of view. Cardiovascular dynamics is found to be characterised by several distinct frequency components, and these are present at each site of the system. The corresponding oscillatory processes are mutually dependent via couplings that lead to amplitude/frequency fluctuations of the characteristic peaks. New studies have been initiated to determine the interactions between the cardiovascular oscillations and some of the brain waves. The work will be reviewed and causal relations will be discussed with a special emphasis on detection of the depth of anesthesia
