  Normal plasma Zero bicarbonate dialysate
pHa 7.35–7.45 10.0
Sodium (mmol/L) [18] 136–145 134
Potassium (mmol/L) [18] 3.5–5.0 3.5
Calciumb (mmol/L) [18] 2.2–2.6 0
Magnesium (mmol/L) [18] 0.8–1.2 1.0
Chloride (mmol/L) [18] 98–106 116 (135.6 final concentration)c
Phosphated (mmol/L) [18] 2.0–4.5 0.5
Lactate (mmol/L) <2.0 3.0
HCO3 (mmol/L)a 22–26 0
  1. aFor a pCO2 of 40 mmHg
  2. bTotal calcium
  3. cModelled chloride concentration was 116 mmol/L. HCl was added so that the dialysate could be analyzed on the blood gas machine resulting in a final concentration of 135.6 mmol/L
