[Methodology and assessment of diagnosis of the hemodynamics of pulmonary circulation].

As to the examination of pulmonary haemodynamics the microheartcatheterization for sounding the right ventricle and the pulmonary artery should be found more acceptance in numerous pulmological and cardiological laboratories for verifying pulmonary hypertension, in preliminary examinations for vitium cordis, in intensive medical care for the continuous registration of haemodynamic parameters or to obtain expert opinion in connection with an occupational disease. Feasible measuring technique and method are put forward for making comparable evaluations. Reference values of haemodynamic parameters at rest and during bicycle exercise in sitting and lying position and regressions calculated on oxygen consumption and on age dependence are set forth. Critical suggestions on obtaining variables are given.
