肺阻抗容积图是阻抗法用于肺循环、肺通气功能检测的一种应用技术,其理论基础是给以一个恒定的微量电流,电流流过胸部肺组织,由于肺组织内含气量、血量的电阻值不同而变动,故称之为阻抗法。肺内气量和血量的平衡是阻抗(Z)水平的一个主要决定因素,因而依据测试对象的各异,在应用上分成肺阻抗血流图、
Impedance volume chart is impedance method for pulmonary circulation, pulmonary ventilation function detection of an application of technology, its theoretical basis is to give a constant micro current, the current flow through the chest lung tissue, the lung tissue due to the amount of gas, blood volume Resistance varies, so called impedance method. The balance of air volume and blood volume in the lungs is a major determinant of the level of impedance (Z) and, therefore, is divided into pulmonary impedance blood flow diagrams on the basis of the differences in the test subjects,
