[Physical exercise tolerance in heart surgery patients during decompensated metabolic acidosis]

Spiroergometric findings obtained before and in different periods (1 month to 8 years) after surgical correction were analyzed in 373 patients with congenital and acquired heart diseases. This allowed the patients to be divided into two groups in terms of their exercise tolerance in decompensated metabolic acidosis. The division should be used to assess the function of the oxygen transport system in cardiac surgical patients who have failed to achieve the "plateau" of oxygen uptake.
