[Correlations among hypoxia, hypercapnia and hyperammonemia in patients with cor pulmonale decompensatum].

The correlation between ammonia concentration of the plasma and blood pH, blood gas values was examined in 28 patients with chronic cor pulmonale decompensatum. In cases with central nervous symptoms were found a significant negative correlation between ammonia concentration of the plasma and arterial oxygen saturation, a significant positive correlation between ammonia concentration of the plasma and paCO2, a significant negative correlation between ammonia concentration of the plasma and arterial blood-pH. In cases without central nervous symptoms, however, no significant correlations was established.
