Time course of pH, bicarbonate (mmol/l), base excess (mmol/l), anion gap (mmol/l), pCO₂ (mmHg), ionized calcium (Ca_ion; mmol/l), sodium (mmol/l) and chloride (mmol/l) at baseline, after 24 hours and after 72 hours of continuous venovenous hemodialysis (CVVHD) treatment time. Forty-three CVVHD runs were included at baseline and at 24 hours, 32 CVVHD runs were included at 72 hours.
