Official Title: Estimation of Cardiac Output by a New Semi-invasive Monitoring System: Accuracy and Limitations
Brief Summary: The aim of the study is to investigate the accuracy of a new semi-invasive cardiac output monitoring system in patients undergoing elective cardiac surgery. The investigators hypothesize that the semi-invasive device may be affected by mean arterial pressure and systemic vascular resistance.
