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 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 ...
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 کاملEffects of arterial oxygen tension and cardiac output on venous saturation: a mathematical modeling approach
OBJECTIVES Hemodynamic support is aimed at providing adequate O2 delivery to the tissues; most interventions target O2 delivery increase. Mixed venous O2 saturation is a frequently used parameter to evaluate the adequacy of O2 delivery. METHODS We describe a mathematical model to compare the effects of increasing O2 delivery on venous oxygen saturation through increases in the inspired O2 fra...
متن کاملUsefulness of central venous oxygen saturation monitoring during bidirectional Glenn shunt.
A PediaSat™ oximetry catheter (PediaSat: Edwards Lifesciences Co., Ltd., Irvine, CA, U. S. A.), which facilitates continuous measurement of central venous oxygen saturation (ScvO2), may be useful for surgery for pediatric congenital heart disease. We used PediaSat during a bidirectional Glenn shunt. The patient was a 13-month-old boy. Under a diagnosis of left single ventricle (pulmonary atresi...
