Validity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content
Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...
متن کاملContinuous monitoring of mixed venous oxygen saturation during aortic surgery.
The correlation between mixed venous oxygen saturation (SvO2) and hemodynamic measurements was studied in 13 patients undergoing descending thoracic aortic aneurysm resection (DTAAR). A significant correlation (p less than 0.05) was found between cardiac index (CI) and SvO2 after the induction of anesthesia and at the end of surgery. However, no significant correlation could be found between Sv...
متن کاملCorrelation of mixed venous and central venous oxygen saturation and its relation to cardiac index
Background and Aim: The clinical applicability of substitution of central venous oxygen saturation for mixed venous oxygen saturations in monitoring global tissue hypoxia is still a matter of controversy. Hence aim of the study is comparison of paired samples of mixed venous and central venous oxygen saturation and comparison in relation to cardiac index in varying hemodynamic conditio s. Mater...
متن کاملInfluence of Cardiac Output on the Correlation between Mixed Venous and Central Venous Oxygen Saturation
Sir,—Because there was close correlation between mixed venous (5vOj) and central venous (5cvOj) oxygen saturations in his study of largely elective cardiac surgical patients, Dr Berridge [1] asserted that 5cvOj may be used to estimate derived oxygen transport variables in emergency situations. This is in disagreement with previous studies [2] and, we feel, merits further comment. Statistically,...
متن کاملInfluence of cardiac output on the correlation between mixed venous and central venous oxygen saturation.
The influence of cardiac output on the correlation between central venous oxygen saturation and mixed venous oxygen saturation was assessed in 51 patients who had both a pulmonary artery catheter and separate central venous catheter in situ. Seventy-six paired samples were taken from the catheters and oxygen saturation measured immediately in a Ciba Corning 2500 Co-oximeter. Cardiac output was ...
