The product has been used preferably by the perfusionists. The performance of the product is advanced and it can be used easily by providing safety at the same time. The product is developed by the continuous improvement of technology which helps to keep the product popular among the perfusionists. The product is a well designed oxygenator with high efficiency and a having low prime volume. During maintaining of high gas transfer of 2.0 to 1.87 m2 the surface area is reduced. The priming volume is reduced by 20% from 310 to 250 cc. The efficiency of heat exchange is improved. The coefficient of heat transfer is increased by 5 percent by the counter flow water path. The removal of air is improved by the venous filtration. Cardiotomy filter has the rating of 30µ. Optimal loading is ensured by the depth filter. The flows are directed to the venous filter.
