Fig. 2. Configuration of autologous transfusion using a cell saver with a rapid infusion system. We applied an autologous transfusion to prevent hypovolemic shock in trauma patients. After the blood was suctioned into the reservoir, it was sent from the reservoir to the cell saver and recycled. The collected blood in the cell saver bag was directly connected to the Rapid Infusion System for infusion directly through the patient’s central line.
