“…Therefore, ScvO 2 has become a metabolic monitoring parameter with extraordinary value in the resuscitation of septic shock patients and a cornerstone of an outcome-oriented algorithm such as early goal-directed therapy [3][4][5]. In this later study, ScvO 2 was continuously measured using a central line with a fiber optic monitor built into it, but there are data showing that there is good agreement between these ScvO 2 measurements and the ones obtained by co-oximetry, which is the method used in most developed countries to measure ScvO 2 [6].…”

“…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].…”

“…Oximetry catheters were designed and developed for use in the intensive care unit and in the operation theatre, and their use in these settings has been repeatedly docu mented [1,4], In 1990. Meissner et al [5] reported that they had diagnosed a ventricular septum rupture using an oximeter catheter.…”

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.

“…In addition, a 7.5-frcnch fiber-optic catheter was placed into the great cardiac vein, and oxygen saturation levels of the great cardiac vein were simultaneously monitored during PTCA, using the Shaw catheter-oximetry system (Oximetrix) [7]. The oximeter was cali brated before insertion.…”

Manifestation of ischemic preconditioning and its mechanisms during percutaneous transluminal coronary angioplasty (PTCA) was evaluated. Twenty-two patients with angina pectoris, who had one-vessel coronary artery disease of the proximal left anterior descending artery but without visual collateral circulation, underwent elective PTCA performed by balloon inflations of 90 s, repeated three times or more. Changes in standard 12-lead electrocardiogram, hemodynamics and oxygen saturation of the great cardiac vein by a fiber-optic catheter were analyzed. Anginal chest pain occurred in 21 patients (95%) during the first balloon inflation, and in only 9 patients (41%) during the third inflation. In comparison with the first inflation, the third produced less shifts in ST junction (p < 0.01) and peak T (p < 0.01), which were measured and averaged by 4 chest leads from V₂ to V₅. The heart rate-blood pressure product during the third inflation was equivalent to that during the first. The great cardiac vein oxygen saturation decreased equally during the first and third inflations. However, the ratio of the saturation at reactive hyperemia after balloon deflation to baseline was higher (p < 0.01) in the third than in the first inflation. The adenosine content of the great cardiac vein measured in 11 patients just prior to balloon deflation was also higher (p < 0.05) in the third inflation than the value in the first. Repeated coronary artery occlusion during PTCA could cause ischemic preconditioning, which may be derived from mechanisms common to accelerated reactive hyperemia, for example an increase in intrinsic adenosine levels.
