摘要 伴肺高压的肺心病与非肺高压的慢阻阻肺在Q-B、B-Y、B-C间期,Q-B/B-Y比值,Hs幅值等项指标差异有极显著性意义,它们与肺动脉压存有中度直线相关,r值在0.332~0.720之间,以Q-B/B-Y最佳。估计肺动脉平均压的回归公式为:PAMP=4.34-4.89Hs-14.69Q-C+4.15Q-B/B-Y(kPa),r=0.78,s=6.24,F=15.33 本公式监测肺动脉压效果满意。 The difference in impedance rheopneumogramm parameters Q-B,B-Y,B-C,Hs,Q-B/B-Y between cor pulmonale with pulmonary hypertension and chronic obstructive lung disease without pulmonary hypertension was of statistical significance.The parameters had higher linear correlation with pulmonary arterial pressure,and their coefficient of correlation ranged from 0.332 to 0.72,P<0.01,with Q-B/B-Y being the best.The regressional equation of PAMP was as follows;PAMP =4.34-4.89Hs-14.69Q-C+4.15Q-B/BlY (kPa),r=0.78,s=6.24,F=15.33,n=34,P<0.01.We are satisfied with the clinical effect of the equation for the calculation of PAMP
