“…Krauss et al [7] reported a good correlation (r = 0.78) between mixed venous oxygen saturation and cardiac index in patients undergoing cardiac or pulmonary surgery. Waller et al [15], studying patients undergoing coronary artery bypass grafting, through continuous monitoring of SvO2 AP using fiber optic catheters, reported good correlation between changes in values of SvO2 AP and CI, with r = 0.69, when there was a variation increase or decrease of 5% or more in SvO2 AP value.…”

“…Krauss et al presented a very high correlation (r = 0.78) between the values of mixed venous oxygen saturation and cardiac index in patients undergoing heart or lung surgery [16]. Waller et al when examining patients undergoing coronary artery bypass surgery, with continuous monitoring of SvO 2 by SGC, found a strong correlation between changes in SvO 2 and CI values: r = 0.69 [17]. The high values of SvO 2 at T 0 may indicate a leak caused by the change of direction of arterial blood flow (shunting) in peripheral tissues.…”

Background: The physiological reaction to a decrease of cardiac output (CO) is an increase of oxygen extraction. Patients with compromised circulation often are not capable of this reaction. The oxygen concentration in such cases will not change with respect to the CO; therefore the mixed venous blood saturation (SvO 2 ) will not be a reliable indicator of the blood flow. Aim of the study: The aim of the study was to determine the reliability of the correlation between hemodynamic parameters and indices of tissue oxygenation in patients undergoing cardiac surgery procedures. Material and methods: We performed a retrospective analysis in 19 patients who required Swan-Ganz catheter (SGC) insertion. Measurements were taken at three time points. Values of cardiac index (CI), mixed venous oxygen saturation (SvO 2 ), oxygen uptake (VO 2 ), oxygen extraction ratio (O 2 ER), and base excess (BE) were analyzed and compared with oxygen partial pressure (PaO 2 ), carbon dioxide partial pressure (PaCO 2 ) and arterial blood saturation (SaO 2 ). Results: Our study revealed an increase of CI, VO 2 and O 2 ER and a decrease of SvO 2 after the operation in comparison with the preoperative period. There was a positive correlation between the trends of SvO 2 and CI before and after the surgery. Conclusions: Correct values of SaO 2 , PaO 2 and PaCO 2 do not mean that the level of subcellular processes associated with the extraction of oxygen proceed in a physiological way. Only SvO 2 and CI results obtained with the SGC make it possible to assess the delivery of oxygen and its consumption at the tissue level.

“…Oximetry catheters utilizing reflectometry for moni toring (mixed venous) oxygen saturation became avail able in the early 1960s [1,2], and came into clinical use over the next 20 years [ 1,[3][4][5][6][7], Initially, the dimensions of these catheters prohibited their use in infants and chil dren, however, oximetry catheters of sufficiently small size for this purpose have recently been developed [8].…”

The aim of this study was to assess the performance of pediatric-size oximetry catheters in diagnostic heart catheterization. Measurements of pressures and oxygen saturations were obtained with oximetry catheters as well as with standard methods during routine heart catheterizations in 10 infants and children with congenital heart defects. Maneuverability of the oximetry catheters was comparable to that of standard Swan-Ganz catheters. Pressure tracings were damped, but mean pressures were undistorted. Oxygen saturation measurements exhibited bias and scatter. It is concluded that no advantage is obtained by the use of oximetry catheters in diagnostic heart catheterization in children and infants.
