Abstract
An integrated blood oxygenation and pump system suitable for use in a sterile field having a low priming volume is provided in which a blood oxygenator portion of the system includes an active element, separate from the pump, that disrupts the development of laminar flow and stagnation zones in the fiber bundle employed for gas exchange. The integrated system enables the pump and oxygenator to be used independently of one another or be rapidly reconfigured to provide both pumping action and blood oxygenation.
