It is vitally important to asses preload an cardiac performance in critically ill patients both intraoperatively and in the intensive care unit. Due to the discussions regarding complications, difficulty in education and increased mortality associated with pulmonary artery catheterization, that is currently used for cardiac performance monitoring, less invasive or noninvasive cardiac output monitoring devices have been delveloped. In general, most methods are based on sound physiologic principle and can be used for following hemodynamic trends. Each of these methods has advantages and disadvantages. The patient outcomes associated with the routine use of these devices are not yet known. It is important for the clinician to understand the strengths and limitations of each device and effectively use the information derived. In this review, minimally invasive or noninvasive cardiac output monitoring devices such as Doppler technology, thoracic electrical bioimpedance, application of indirect Fick principle and transpulmonary termodilution/pulse contour analysis methods will be focused on. Basic principles underlying these new technologies, the relative advantages and limitations associated with these devices will be summarized.
