[Extra-corporeal circulation. Experimental study. Comparative study of various oxygenators (author's transl)].

An experimental study of three different types of oxygenator was carried out in the dog during two hours extra corporeal circulation. The hemodynamic aspects and the characteristics of pulmonary elasticity that a previous study permitted us to choose as controls of the quality of extracorporeal perfusion, were studied. The results show that the pulmonary arterial resistances and the indices of pulmonary compliance do not recover during E.C.C. to their initial values, in the case of an E.C.C. using a bubble oxygenator. These results should be taken into consideration in the choice of the most suitable oxygenator.
