Cell saver

A cell saver, also known as an autotransfusion device, is often used during cardiopulmonary bypass (CPB) procedures. It's a medical device that collects and processes blood lost during surgery, particularly in procedures involving significant blood loss.

The cell saver works by collecting the blood from the surgical field, filtering out any contaminants or debris, and then reinfusing the cleaned blood back into the patient. This helps to minimize the need for donor blood transfusions, reduce the risk of complications associated with transfusions, and maintain the patient's blood volume.

The collected blood is processed to separate red blood cells from other components, like plasma and platelets. This concentrated red blood cell suspension can then be returned to the patient, which can be especially beneficial in surgeries where a significant amount of blood loss is anticipated.

Overall, the cell saver is a valuable tool in CPB procedures and other surgeries involving substantial blood loss, as it helps to conserve the patient's own blood and reduce the reliance on external blood sources.
