Perfusion Quality Score (P.Q.S), in Material Selection before of Cardiopulmonary Bypass

There is a large number of systems and technique patterns that deal with the extracorporeal circulation technique to reduce the biologic impact of the system. Nevertheless, there is no such thing as an evaluation quality score of the pathophysiology of the CPB cardiopulmonary bypass, as our world consists of a wide range of variants of the extracorporeal circulation, which are not provided with a quality yardstick.This work seeks to create a quality score, aiming at measuring the extra-corporeal circulation technique and its impact, linked to an inspection of the scientific literature in particular, to achieve goal directed perfusion.The studies concerning the optimisation of extracorporeal circulation techniques have been analysed to reduce the pathophysiological consequences of conventional systems. Also analysed were studies on patients with low- and high-risk candidates, candidates for cardiac surgery, who used special extracorporeal circulation techniques aimed at containing the pathophysiological response, cohort studies, prospective studies, retrospective studies and meta-analysis. This paper is meant to create a quality score of the components of the cardiopulmonary bypass, stimulating the qualitative selection of the materials of the techniques and methods
