Some experimental aspects of using lungs as biological oxygenator in extracorporal circulation

Exposing problem of oxygenators in extracorporal circulation authors consider screen and membrane as the best, in spite of some disadvantages from which the haemolysis is the most cumbersome. In attempt to find the way of solution of this problem, authors have made a number of experiments in animals where they have conducted extracorporal circulation in such way that blood has been oxygenated in own lungs of an animals. Two types of bypass were examined as: right to right bypass (vv. cavae-pulmonary artery), right to right bypass as exposed with possibility of interconnection with classical extracorporal circulation, and finally bypass of the left and right heart. Exposing their experience and results authors consider that use of lungs as biological oxygenator in extracorporal circulation has its justification according to achieved results. In spite of some problems which need further elaboration such experiments are the motive for more work and reflexion in this type of problem.
