Splet12. jun. 2015 · From looking at the SvO 2 alone, it is impossible to determine whether the cardiac output is high or low. For example, an SvO 2 of 50% may be due to a low cardiac output, or a high tissue metabolic demand, or to a low arterial oxygen content. Serial measurements of SvO 2 cannot describe changes in cardiac output. Splet31. jan. 2024 · Mixed venous oxygen saturation (SvO2) is the percentage of oxygen bound to hemoglobin in blood returning to the right side of the heart. This refects the amount of oxygen “left over” after the tissues remove what they need. It is used to help us to recognize when a patient’s body is extracting more oxygen than normally.
