Comment:

The intentional dilution of blood volume often is referred to as acute normovolemic hemodilution (ANH) anemia. ANH is a technique in which whole blood is removed from a patient, while the circulating blood volume is maintained with acellular fluid. Blood is collected via central lines with simultaneous infusion of crystalloid or colloid solutions. Collected blood is reinfused after major blood loss has ceased, or sooner, if indicated. Blood units are reinfused in the reverse order of collection. Under conditions of ANH, the increased plasma compartment becomes an important source of O2, which is delivered to the tissues.
