Transfuse over a 2-4 hours..
One unit of packed red blood cells (PRBC) typically contains about 250 to 300 cc (milliliters) of blood. The exact volume can vary slightly depending on the collection and processing methods used. PRBCs are concentrated red blood cells with most of the plasma removed to enhance the oxygen-carrying capacity.
Most doctors do not give lasix before a transfusion, but give it between 2 units of PRBC to prevent fluid volume overload.
Packed red blood cells (PRBCs) should ideally be administered within 30 minutes of receiving them from the blood bank to minimize the risk of bacterial growth and ensure the integrity of the blood product. Once the transfusion has started, it should be completed within 2 to 4 hours. It's important to monitor the patient closely during the transfusion for any adverse reactions.
Hemoglobin molcules account for more than 95 percent of Erythrocyte's proteins. There are approx. 280 million moleules of hemoglobin in each RBC. hemoglobin also carries about 23 percent of carbon dioxide transposted in the blood.. And the bindings of amino acids to carbon dioxide or globin subunits is reversable

A good rule of thumb is 1 Unit of PRBCs will raise an adult's Hgb by 1 g/dl or their Hct by 2~3%. For pediatrics, a 10 ml/kg transfusion will increase Hgb by 3 g/dl and Hct by 10% These are approximations, of course, and depend on the size of the patient, the exact Hct of the transfused blood, and red blood cell survival after transfusion. In general, a unit of PRBCs is ~300 ml and has a Hct of 70% Ref: "Clinical Anesthesiology," E. Morgan, M. Mikhail, M. Murray. 4th ed.
