肺阻抗血流图是一种用电阻抗的变化,来反映肺血管容积变化的描记图。国内自1976年李希臻报道慢性阻塞性肺病的肺血流图观察后,特别是全国第二次肺心病专业会议以来,对肺阻抗血流图及其微分图,这一无创伤技术的研究,受到广泛重视,为探讨其对慢性肺心病 (简称肺心病)的诊断价值,我们在用电桥式心阻抗仪做正常人、慢支炎、肺气肿、肺心病的肺血流图初步观察基础上,自1982年改用直接
Pulmonary impedance The blood flow diagram is a trace of changes in electrical impedance that reflects changes in pulmonary vascular volume. Since 1976, Li Xizhen coverage of chronic obstructive pulmonary disease pulmonary blood flow diagram observed, especially the second national pulmonary heart disease professional conference since the pulmonary impedance blood flow diagram and its differential graph, this non-invasive technology, by Wide attention, in order to explore its diagnostic value of chronic pulmonary heart disease (referred to as pulmonary heart disease), we use the bridge impedance instrument for normal people, chronic bronchitis, emphysema, pulmonary heart disease preliminary observation of pulmonary blood flow diagram On, switched to direct since 1982
