Venous Oxygen Saturation - StatPearls - NCBI Bookshelf
WEBOct 24, 2022 · Venous oxygen saturation (SvO2) measures the blood's oxygen content returning to the right side of the heart after perfusing the entire body. When the oxygen supply is insufficient to meet the metabolic demands of the tissues, an abnormal SvO2 ensues and reflects an inadequacy in systemic oxygenation.

WEBOct 2, 2023 · Co-oximeter: a device that uses spectrophotometry to measure relative blood concentrations of oxyhemoglobin, carboxyhemoglobin, methemoglobin, and reduced haemoglobin.
PulmCrit – Central venous oxygen saturation: signal or noise?
WEBJul 17, 2017 · The central venous oxygen saturation is a poor estimator of the actual mixed venous oxygen saturation. For example, one study comparing cvO2% vs. mvO2% in sepsis found that the 95% confidence interval for the difference between both values was between -12% and 15.5%:
Oxygenation Status and Pulse Oximeter Analysis
WEBJun 11, 2023 · This activity reviews pulse oximeters' functioning, ubiquity, and ability to supply oxygenation information. Additionally, the discussion includes co-oximeters, which differ from pulse oximeters and offer insights into functional and fractional saturation and the detection of dyshemoglobinemias.
Central venous oxygen saturation (ScvO2) • LITFL • CCC …
WEBCentral venous oxygen saturation (ScvO2) surrogate for SvO2 thus provides a surrogate measure of oxygen flux, reflecting the balance between oxygen delivery (DO2) and consumption (VO2).
Focus on Diagnosis: Co-oximetry | Pediatrics In Review
WEBFeb 1, 2007 · A co-oximeter is a blood gas analyzer that, in addition to the status of gas tensions provided by traditional blood gas measurements, measures concentrations of oxygenated hemoglobin (oxyHb), deoxygenated hemoglobin (deoxyHb or reduced Hb), carboxyhemoglobin (COHb), and methemoglobin (MetHb) as a percentage of the total hemoglobin concentration ...
