A typical volume of blood in the human body is about 5 L. A certain percentage of that volume (called the hermatocrit) consists of red blood cells (RBCs); typically the hermatocrit is about 45% in males. Suppose that a surgery takes four hours and a male patient bleeds 2.5 L of blood. During surgery the patient's blood volume is maintained at 5 L by injection of saline solution, which mixes quickly with the blood but dilutes it so that the hermatocrits decreases as time passes. 1. Assuming that the rate of RBC loss is proportional to the volume of RBCs, determine the patient's volume of RBCs by the end of the operation.
