An important principle in the management of electrolytes with CRRT is that “you get what you replace”. With hemofiltration all electro-lytes are freely removed (sieving coefficients near 1) and thus, over time and assuming no large intake or other losses, plasma concentra-tions will approach those of the replacement fluid. The rate at which electrolytes change is determined by how different the plasma con-centration is relative to that in the replacement fluid and the rate of fluid replacement deliv-ered.
