This diagram shows the possibilities of advanced hemodynamic measurements with the central venous catheter (cvc). In addition to measuring the central venous pressure (cvp), the central venous saturation (svo2) can be determined directly via the cvc. If the arterial oxygen supply is also known (with an arterial line), the cardiac output can also be calculated using AVDO2 (Fick principle). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4282012/
