肺血流图(Rheopneumography)亦称为肺阻抗图(Impedauce pneurnography)。目前国内已趋于一致,称为肺阻抗血流图(以下简称肺血图)。肺血图主要反映肺部血流动力学变化,同时亦可作为肺通气功能的指标。该图舒张波的变化反映左心功能状态,而收缩波则反映右心的功能状态,并可根据肺血图基础阻抗值(Zo)的变化反映胸腔内 Pulmonary blood flow map (Rheopneumography) also known as the lung impedance map (Impedauce pneurnography). At present, China has become the same, known as pulmonary impedance blood flow diagram (hereinafter referred to as lung blood). Pulmonary blood flow mainly reflects pulmonary hemodynamic changes, but also can be used as an index of pulmonary ventilation. The changes in diastolic waves reflect left ventricular functional status, and contractile waves reflect the functional status of the right heart, and can reflect the change of the basic impedance value (Zo)
