Perspectives on the interpretation of continuous mixed venous oxygen saturation.
Continuous measurement of mixed venous oxygen saturation (SvO2) is a beneficial method for evaluating overall dynamic tissue oxygen balance in critically ill patients. Several important factors, however, may influence the accurate analysis of SvO2 data trends. In this review we highlight these factors and support cautious interpretation of SvO2 in conjunction with other available patient data and with strict attention to the clinical value and limitations of the parameter.
