Results from blood gas analysis obtained after hemodialysis of swine blood under different treatment settings with ADVOS. Experiments with dialysate pH 10 were performed with the basic concentrate without Na₂CO₃ (BC-Bic 0). The value “10-P” corresponds to the experiments where CO₂ was supplied as long as physiological blood gas values were maintained (pH 7.35–7.45, pCO₂ 35–45 mmHg, HCO₃⁻ 22–28 mmol/l) and not only blood pH. Mean ± SD.1, p < 0.05 for CO₂ removal between consecutive dialysate pH settings among the same blood flow; 2, p < 0.05 for CO₂ removal between consecutive blood flows among the same dialysate pH setting; 3, p < 0.05 for CO₂ removal between consecutive concentrate flows among the same blood flow and dialysate pH setting
