	Utilizing a special double lumen suction tubing, fluid is aspirated from the operative field, and is mixed with an anticoagulant solution. Collected fluid is filtered in a sterile [[cardiotomy]] reservoir. The reservoir contains filter and has a capacity of between two and three liters of fluid. When a volume adequate to fill the wash bowl has been collected, processing may begin. The volume required to fill the bowl is dependent on the concentration of red cells collected and size of the centrifuge wash bowl.

When a volume adequate to fill the wash bowl has been collected, processing may begin. The volume required to fill the bowl is dependent on the concentration of red cells collected (hematocrit) and size of the centrifuge wash bowl. But if the patients HCT (hematocrit) is normal, the amount needed to process a unit is roughly two times the bowl volume. Therefore, if the centrifuge processing bowl size is 250 ml, you will need roughly 250-300 ml of blood.

	The ~~sole~~ disadvantage of autotransfusion is the depletion of [[Blood plasma\|plasma]] and [[platelet]]s. The washed autotransfusion system removes the plasma and platelets, to eliminate activated [[clotting factor]]s and activated platelets which would cause [[coagulopathy]] if they were reinfused to the patient. This disadvantage is only evident when very large blood losses occur. The autotransfusionist monitors blood loss and will recommend the transfusion of fresh frozen plasma (FFP) and platelets when the blood loss and return of autotransfusion blood increases. Typically the patient will require FFP and platelets as the estimated blood loss reaches half of the blood volume of the patient.

			It should be noted that when a patient recieves banked donor blood that this blood is also in fact, only packed red blood cells, and has no coagulation factors. Therefore, if a patient loses more than half of their total blood volume, they will need to recieve FFP and platelets no matter if they are getting their own blood back or donated homologeous blood.
