The Swan-Ganz catheter is the gold standard to measure cardiac output during liver transplantation surgery. This is an invasive hemodynamic monitoring system. The VenArt Cardiac Output (Mespere LifeSciences, Waterloo, Canada) is a new, innovative and non-invasive device that permits hemodynamic monitoring. With a software based on Fick's principle it is able to calculate cardiac output, cardiac index and continuous cardiac output. The hypothesis of this study is to investigate the precision and accuracy of this method versus the standard of care during liver transplantation.
