  1. Data are mean ± SEM for n = 5-8 experiments each, derived 10 min after initiating each experimental condition. No difference of the respective parameters could be detected during the course of the experiment (data not shown). In hypercapnia with normal pH, pH was corrected to the given values by the addition of sodium bicarbonate.
  2. * indicates significant differences as compared to normoxia or normocapnia.
