Cell Saver blood-recovery system (Haemonetics)

I was reading about a medical case the other day in the New England Journal of Medicine about a "Pregnant Woman with Abdominal Pain and Fluid in the Peritoneal Cavity." The management of this patient involved the use of the Cell Saver blood-recovery system (Haemonetics). The Cell Saver system recovered approximately 600 ml of red cells. That's quite impressive. Here's some information about this technology (from the company's website:

Haemonetics pioneered intraoperative cell salvage. Since its introduction in 1972 our Cell Saver® Autologous Blood Recovery system led the industry to become the standard of care.

The Cell Saver 5+ system is designed for surgeries like CABG, valve replacement, trauma, transplant, and other procedures where medium- to high-volume blood loss occurs. With the ability to deliver between 50-60% hematocrit and to remove nearly all traces of undesirable components such as free hemoglobin, the Cell Saver system is the standard of care and a critical tool to help avoid unnecessary allogeneic transfusions. And in a recent lab test, SmartSuction Harmony® surgical suction system significantly reduced hemolysis. Based on this finding, when a SmartSuction Harmony device is used with the Cell Saver system there may be an increase in the number of viable red blood cells reinfused to patients.
