The optimal cell salvage settings to maximize hematocrit and minimize potassium using the Cobe BRAT2 Autologous Blood Recovery Unit

The objective was to determine the optimal cell saver device settings (infusion rate and wash rate) at which hematocrit is preserved and potassium and lactate are removed from banked red blood cells.Design: Red cells were washed using the Cobe BRAT 2 Autologous Blood Recovery Unit and sampled for electrolyte composition and hematocrit pre and post-wash.Setting: This was a single-center study.Interventions: Red cells were washed using at six infusion rates (100 to 1000 mL/min) and six wash rates (100 to 1000 mL/min) for a total of 36 combinations.
