The effects of the Gemini PC-2 linear peristaltic infusion device on the integrity of packed red blood cells (RBC) and whole blood products are reported. Thirty-eight units of blood products were infused at rates of 999, 100, 50, and 5 mL/hr under simulated clinical conditions. To evaluate the effect of hematocrit on cell survival, fresh and stored packed RBCs preserved with adenine-saline 3 (AS-3) and fresh and stored packed RBCs and fresh and stored whole blood preserved with citrate-phosphate-dextrose-adenine 1 (CPDA-1) were used. No two units tested came from the same donor. Plasma potassium and plasma free hemoglobin concentrations were determined before and after simulated infusion for 80 experimental runs. Preinfusion plasma potassium and free hemoglobin concentrations varied significantly among the blood products. Stored products were associated with higher plasma potassium and free hemoglobin levels than fresh units, both before and after infusion. Concentrations also differed significantly between AS-3-preserved and CPDA-1-preserved fresh and stored packed RBCs. Infusion did not change plasma potassium values appreciably under any conditions. Plasma free hemoglobin increased in the fresh products only. Donor-specific differences were significant for potassium but not for free hemoglobin. There was no significant effect of infusion rate on either biochemical marker. In all the experimental runs, less than 0.01% of cells were lysed. The Gemini PC-2 linear peristaltic infusion device delivered a variety of blood products at a wide range of infusion rates without inducing a substantial degree of hemolysis.

D011188 Potassium An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D001803 Blood Transfusion The introduction of whole blood or blood component directly into the blood stream. (Dorland, 27th ed) Blood Transfusions,Transfusion, Blood,Transfusions, Blood
D006400 Hematocrit The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
