Blood first passes to plasma filter. Plasma then passes on to immunoadsorption column before returning to patient. As the plasma is passing through one column, the second column is being regenerated. Once the first column is saturated the flow switches to the second column while the first is then regenerated.
Residual CPB blood is fairly dilute ([Hb] = 6–9 g/dL; 60–90 g/L) compared to normal values (12–18 g/dL; 120–180 g/L) and can also contain potentially harmful contaminants such as activated cytokines, anaphylatoxins, and other waste substances that have been linked to organ edema and organ dysfunction and need a diuretic to reverse.

[1] The patient's blood is removed and replaced by donated blood or blood components. This exchange transfusion can be performed manually or using a machine . [2]
Stem cells are kind of wild and can be used to create just about anything. Now, scientists have successfully created blood in a lab using the wundermaterial. As New Scientist points out, this ...

The blood is being produced for the Defense Advanced Research Projects Agency by Arteriocyte. The Food and Drug Administration has examined and approved the safety of this blood from previously submitted O-negative blood. Using this particular artificial blood will reduce the costs per unit of blood from $5,000 to equal or less than $1,000. [36]
Patients with poor oxygen saturation may need more blood. [5] The advisory caution to use blood transfusion only with more severe anemia is in part due to evidence that outcomes are worsened if larger amounts are given. [8] One may consider transfusion for people with symptoms of cardiovascular disease such as chest pain or shortness of breath. [4]
