某些肺循环病理改变所致的心、肺疾病以及心功能不全等都可导致肺阻抗发生改变。因此进行肺阻抗研究具有重要的临床价值和广阔前景。作为人体循环系统的重要部分——肺循环以前缺少简便、无创伤的客观观察方法，以致对其规律的研究和所知较少。右胸电阻抗／导纳图技术的应用为 Some pulmonary circulation pathological changes caused by heart, lung disease and cardiac insufficiency can lead to changes in lung impedance. Therefore, the study of pulmonary impedance has important clinical value and broad prospects. As an important part of the circulatory system of the human body - the pulmonary circulation has previously lacked a simple, noninvasive and objective method of observing the lungs so that there is little research into its regularity.
