Improved removal of middle molecules Loss of protein About 1 g/hr. of treatment 3-6 g/treatment or 10-20 g/week About 1 g/hr. of treatment 20-30 g/day for CAPD Rate of removal of potassium Dependent on concentration of K in dialysate versus its concentration in the blood. The rate of removal of K is highest at the start of the treatment and tapers off owing to equalization of the concentration of K in dialysate and blood.
