ABSTRACT
In order to investigate the relation of impedance rheopneumogram with pulmonary hemodynamics and right ventricular function in patients with chronic obstructive pulmonary disease (COPD), we measured impedance rheopneumogram and did right heart catheterization in 150 COPD patients simultaneously both at rest and after exercise. The results showed that impedance rheopneumogram was mainly influenced by right ventricular after-load, while the influences of right ventricular pre-load, right ventricular contraction, right ventricular stroke work index and cardiac output were rather small, suggesting that in COPD patients impedance rheopneumogram is valuable in predicting pulmonary arterial pressure noninvasively, but not so use in judging the right ventricular function.
