Blood gas analysis in chronic obstructive pulmonary disease with pulmonary hypertension

Abstract

This article discusses the course of pulmonary hypertension in chronic obstructive pulmonary disease, in particular the relationship between systolic pressure in the lungs and blood gases, as well as a comparative analysis of bosentan and sildenafil. The results of the study showed that in chronic obstructive pulmonary disease with pulmonary hypertension in stages II-III-IV of the disease, there are the following correlations in accordance with systolic pressure in the pulmonary artery, a positive relationship in the II degree with pCO2 (r = 0.3), (P < 0.03), negative pO2 (r = -0.3, P < 0.02), also grade III positive relationship with pC02 (r = 0.54, P < 0.001) and negative with pO2 and sO2 (r = -0.6, P < 0.001 and r = respectively).
