Comparison of central-venous to mixed-venous oxygen saturation during changes in oxygen supply/demand.
Because central venous O2 saturation (superior vena cava, ScvO2) can be monitored with less patient risk than mixed venous O2 saturation (pulmonary artery, SvO2), we examined the correlations between SvO2 and ScvO2 over a broad range of cardiorespiratory conditions, including hypoxia, hemorrhage, and resuscitation in anesthetized dogs. The correlation coefficient (r) between SvO2 and ScvO2 in 1...
متن کاملTrends but not individual values of central venous oxygen saturation agree with mixed venous oxygen saturation during varying hemodynamic conditions.
BACKGROUND Previous studies found contradictory results regarding the question whether mixed venous oxygen saturation (Svo2) and central venous oxygen saturation (Scvo2) are equivalent. The inconsistency of study results may result from different study designs and different, partly questionable, statistical approaches. METHODS The authors performed a prospective clinical trial comparing indiv...
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 ...
