Figure 1 The miniaturized CPB system. The double roller pumps are mast-mounted remote pump heads that can be positioned almost unrestrictedly. The arterial pump is placed very close to the outlet of the venous reservoir and to the inlet of the oxygenator/heat exchanger (priming volume, 31 mL). The arterial line filter has a priming volume of 16 mL. The cardiotomy suction pumps are in proximity to the cardiotomy reservoir inlets. All tubing connections have internal diameters of 3/16 inch, with the exception of the segment of the arterial pump, which consists of 1/4-inch silicone tubing.
