Abstract
A method is provided for priming a hollow fiber oxygenator which is integrated with a hollow tube heat exchanger. A closed priming circuit is created between a cardiosurgery reservoir, the combined hollow fiber oxygenator and heat exchanger and a vacuum source. Vacuum pressure is applied to the closed priming circuit to evacuate the residual air from the circuit. Priming solution is released from the cardiosurgery reservoir and fills the evacuated closed priming circuit.
