Fig. 2From: Peripheral measurements of venous oxygen saturation and lactate as a less invasive alternative for hemodynamic monitoringTrending ability of peripheral and central venous oxygen saturation at different time points. Four quadrant plot depicting trending ability of peripheral compared with central venous oxygen saturation between the different sampling points (preoperative, upon arrival to the ICU and 3–4 h postoperative). A total of 316 paired measurements were inserted in the four quadrant plot. The x axis represents the delta SpvO2 and the y-axis represents the delta ScvO2. Abbreviations: SpvO2: peripheral venous oxygen saturation. ScvO2: central venous oxygen saturationBack to article page
