2 Fig. 1 Perfusion and drainage in retrograde cerebral perfusion through an SVC cannula. Only the aortic cannula (AO) was opened and directed by gravity to the cardiotomy reservoir while the caval cannulas were clamped. Returned blood (dark gray) was perfused through an oxygenator into both the internal maxillary venous cannulas with a separate pump (light gray).

3 Fig. 2 Returned blood flow rates and perfusion blood flow rates during hypothermic (20° C) cardiopulmonary bypass at 1000 ml/min (CPB) and hypothermic (20° C) retrograde cerebral perfusion (RCP) at an external jugular venous pressure of 15, 20, 25, 30, or 35 mmHg.
