A comparison of hemolysis and red cell mechanical fragility in blood collected with different cell salvage suction devices

Abstract

Although the variable-pressure device produced a significant reduction in hemolysis during one-pass blood collection, the clinical significance of this reduction is not clear. In relative terms, the variable-pressure device would recover an extra 10 mL of RBCs for every liter of salvaged RBCs, which is negligible compared to the blood loss in major surgery.
