【摘要】：目的:生物电阻抗法是生物医学检测的基本方法 ,利用人体组织与器官的电特性及其变化规律提取与人体生理、病理状况相关的生物医学信息的检测技术,具有无创、无害、廉价、操作简单和功能信息丰富的特点,而且测量结果准确、测量可重复性高等优点。所以,基于生物电阻抗的医学检测技术越来越多的应用于研究与临床中。方法:本文阐述了生物电阻抗法用于生物医学检测的几个方面,即电阻抗式呼吸监测、阻抗血流图、生物电阻抗法人体成分检测、生物电阻抗法胃动力学检测、生物电阻抗法人体心肺复苏评估、电阻抗断层成像技术等。结果:虽然生物电阻抗法测量影响因素很多,包括电极极化和人体接触阻抗、系统电极间相对固定的位置等系统电极的影响;运动对生物阻抗法的影响、人体测量时食物的摄入量、人体测量时姿势的变化等受测者的测量时状态对测量结果的影响。但是,生物电阻抗法在生物医学测量中依然占有重要的地位。结论:生物电阻抗法是生物医学检测的基本方法。通过本文的综述对于我们借助于生物电阻抗测量测量人体生理及病理信息具有具有的借鉴意义。
[Abstract]:Objective: bioelectric impedance method is the basic method of biomedical detection. It is noninvasive and harmless to extract biomedical information related to human physiology and pathology by using the electrical characteristics of human tissues and organs. The advantages of cheap, simple operation and abundant function information, and the advantages of accurate measurement results and high repeatability. Bioelectrical impedance based medical detection technology is more and more widely used in research and clinic. Methods: in this paper, several aspects of biological impedance method used in biomedical detection, namely electrical impedance respiratory monitoring, impedance blood flow graph, are described. Results: although there are many factors affecting the measurement of bioelectrical impedance, such as human body composition detection, bioelectrical impedance method gastric dynamics test, biological electrical impedance method human cardiopulmonary resuscitation evaluation, electrical impedance tomography technology, etc. The effects of electrode polarization and human contact impedance, the relative fixed position between the system electrodes, the effect of exercise on the biological impedance method, the intake of food in human body measurement, The change of posture in anthropometry and the effect of the measured state on the measurement results. However, Bioelectrical impedance method still plays an important role in biomedical measurement. Conclusion: bioelectrical impedance method is the basic method of biomedical detection. The body physiology and pathological information have reference significance.
