Abstract
A method for improving priming of an integrated oxygenator and heat exchanger which includes pretreating the integrated hollow fiber oxygenator and heat exchanger device with a surfactant. Pretreating the device coats the interior surfaces of the integrated hollow fiber oxygenator and heat exchanger with the surfactant, which facilitates the removal of entrapped air. An integrated hollow fiber oxygenator and heat exchanger having a surfactant coating on the interior surfaces is provided which subsequently allows for more efficient priming with an aqueous priming media.
