用肺血流图法测定慢性阻塞性肺病(下简称慢阻肺)、肺心病患者各17例的肺血管顺应性(Cpv),同时测定了肺血管总阻力(TPR)。肺心病组Cpv为23.55ml/kPa,TPR为42.09kPa·s/L;慢阻肺组Cpv为28.28ml/kPa,TPR为24.37kPa·S/L。两组差异有极显著性意义(P<0.01)。肺心病组TPR增高是其Cpv下降程度的4.36倍。Cpv下降是肺心病发生的一个次要因素。Cpv与肺血流图指标Q-Bi、B-Y、P_2-Y、Q-B/B-Y等具有较高的相关性,相关系数在0.335～0.664之间,Cpv仅对肺血流图产生中度影响。
Pulmonary vascular compliance (Cpv) was measured in 17 COPD patients with chronic obstructive pulmonary disease (COPD) and pulmonary heart disease (COPD), and total pulmonary vascular resistance (TPR) was also measured by pulmonary blood flow diagram. The CPV of pulmonary heart disease group was 23.55ml / kPa, the TPR was 42.09kPa · s / L, the Cpv of COPD group was 28.28ml / kPa and TPR was 24.37kPa · S / L. There was significant difference between the two groups (P <0.01). Pulmonary heart disease group increased TPR is 4.36 times the degree of decline in Cpv. Cpv decline is a secondary factor in the occurrence of pulmonary heart disease. Cpv and pulmonary blood flow indicators Q-Bi, B-Y, P_2-Y, Q-B / B-Y and other high correlation between the correlation coefficient of 0.335 ~ 0.664, Cpv only moderate effect on pulmonary blood flow diagram.
