Abstract
A condensed circuit for cardiopulmonary bypass includes an air removal system located after the junction of a shunt line and the reservoir, but before the perfusion pump. Both passive and active systems are described. The dual role of the air removal system is to remove/aspirate micro-air bubbles from the venous side of the circuit and to prevent large air boluses from entering the centrifugal pump and stopping the pump.
