肺血流图即肺电阻图,是利用机体组织中血液和组织液对电流阻抗最小、导电度最大的特点及其能使通过肺组织的无害的微弱的高频电流发生强弱的改变,通过放大和记录仪器描记下来,藉此研究肺血容量波动情况及肺动脉供血状态。近年来国内已有报道,但由于仪器规格不统一,正常值也不统一。我们测定了100例正常人的肺血流图,并与肺气肿和肺心病病例进行对比观察,以探讨肺血流图对肺心病的诊断价值。
Pulmonary blood flow diagram that is the lung resistance diagram is the use of blood and tissue fluids in the body of the current impedance of the smallest, the most conductive characteristics and its ability to pass through the lung tissue harmless weak high-frequency current intensity changes through Zoom in and record the instrument down, to study the fluctuation of pulmonary blood volume and pulmonary artery blood supply. In recent years, China has been reported, but because of the instrument specifications are not uniform, the normal value is not uniform. We measured the lung blood flow of 100 normal people, and compared with emphysema and pulmonary heart disease cases to explore the diagnostic value of pulmonary blood flow diagram of pulmonary heart disease.
