10 Σεπ 2024 · 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.
Central 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).
8 Ιουλ 2013 · The aim of this literature review was to provide a clear definition of central venous oxygen saturation (ScvO 2), highlight the differences between ScvO 2 and mixed venous oxygen saturation (SvO 2), show how it can be used clinically and the effect central venous oxygen saturation has on mortality.
24 Οκτ 2011 · Venous oxygen saturations have been the subject of research for over 50 years, but especially over the past decade the amount of literature describing changes in ScvO 2 and SvO 2 in critically ill patients, including high-risk surgical patients, increased substantially.
10 Νοε 2014 · Central venous oxygen saturation (ScvO 2) >70% or mixed venous oxygen saturation (SvO 2) >65% is recommended for both septic and non-septic patients. Although it is the task of experts to suggest clear and simple guidelines, there is a risk of reducing critical care to these simple recommendations.
Correct clinical interpretation of SvO2, or its properly measured ScvO2surrogate, can be used to (1) estimate cardiac output using the Fick equation, (2) better under-stand whether a patient’s oxygen delivery is adequate to meet their oxygen demands, (3) help guide clinical practice, particularly when resuscitating patients using validated early...
24 Οκτ 2011 · Venous oxygen saturations represent this relationship between oxygen delivery and oxygen demand and can therefore be used as an additional parameter to detect an impaired cardiorespiratory reserve. Before appropriate use of venous oxygen saturations, however, one should be aware of the physiology.
