From: End expiratory oxygen concentrations to predict central venous oxygen saturation: an observational pilot study

Figure 3

Regression analysis of the predicted ScVO2 versus measured ScVO2. The Y-axis values were derived from the equation Predicted ScVO2 = -78.1 + 1.2(EtCO2) + 0.95(EtO2), and the X-axis values were the average of two duplicate oxygen saturation measurements of central venous blood specimens obtained from a hemodialysis catheter. EtO2 – end-tidal oxygen; EtCO2 – end-tidal carbon dioxide; ScVO2 – central venous oxygen saturation.
