Multielectrode Impedance-Based Ventilation Monitoring

这项拟议的工作是对当前研究的继续，目的是将阻抗气体描记发展为一种新的诊断工具。研究人员建议制作一种带有多个电极的背心状服装，通过这些电极可以监测呼吸过程中胸部的阻抗变化。利用数值技术，可以得到胸腔的“阻抗图像”。该装置对于准确监测潮气量随时间的变化应该是非常有用的；拟议的研究可能会产生新一代呼吸暂停监测仪。

The proposed work is a continuation of current research to develop impedance pneumography as a new diagnostic tool. The investigators propose to build a vest-like garment with multiple electrodes through which impedance changes across the chest can be monitored during breathing. Using numerical techniques an "impedance image" of the thorax may be obtained. The device should be very useful for accurately monitoring changes in tidal volume as a function of time; a new generation of apnea monitors may result from the proposed research.
