32 cases of obliterative pulmonary vascular disease were studied by comparing, the results of pulmonary impedance plethysmogram (PIP) and hemodynamic parameters obtained by catheterization. It is shown that the main PIP feature of obliterative pulmonary vascular disease is a delayed peak of delta Zmax, and QZM is correlated with pulmonary artery pressure. Two sets of regression equations were established with parameters of PIP for the estimation of pulmonary artery pressure in obliterative pulmonary vascular disease.
通过比较32例闭塞性肺血管疾病患者的肺阻抗容积图（PIP）结果与通过导管插入术获得的血流动力学参数进行了研究。结果表明，闭塞性肺血管疾病的主要PIP特征是ΔZmax峰值延迟，且QZM与肺动脉压力相关。利用PIP参数建立了两组回归方程，用于估计闭塞性肺血管疾病中的肺动脉压力。
