Figure 4From: A preliminary study on the monitoring of mixed venous oxygen saturation through the left main bronchusThe accuracy of the new method in hemodynamically stable status. Shown is a Bland–Altman graph comparing the difference between mixed venous oxygen saturation through the left main bronchus (SpO2trachea) and oxygen saturation from pulmonary artery samples (SvO2blood) versus the mean oxygen saturation by the 'gold standard' and the new method in hemodynamically stable status.Back to article page
