Continuous central venous oxygenation measurement by CeVOX in patients undergoing off-pump coronary artery bypass grafting

Less invasive measurement of central venous O2 saturation(ScvO2) has shown to be a valuable alternative to the determination of mixed venous O2 saturation for monitoring of O2 supply/demand [1,2]. The aim of this study was to compare ScvO2 measured continuously by the new CeVOX (Pulsion Medical System, Munich, Germany) device (CScvO2) with ScvO2 determined by blood gas co-oximetry (BScvO2).
