[Effect of hemodialysis on the functional status of small airways and partial pressure of oxygen and carbon dioxide in the blood of patients with chronic uremia].

In 18 patients with chronic uremia the effect of 4 hour hemodialysis on VC, FEV1, PEF, MEF25, MEF50, MEF75, PaO2 and PaCO2 were analysed. Significant falls in PaO2 and PaCO2 were found after ending the four hour long hemodialysis. Only nonsignificant changes in the other parameters were observed. The results of this study demonstrates the role of ventilatory disturbances of small airways in the pathogenesis of dialysis induced hypocapnia and hypoxemia.
