Femoral venous oxygen saturation may still be a valuable tool.
We thank Dr Das for his interest in our case series published in CHEST (May 2010). 1 In his letter, Dr Das emphasizes some of the key clinical data presented in Table 1 of our report on six patients with both pandemic 2009 infl uenza A(H1N1) (A[H1N1 ]) and cardiac dysfunction. We agree that other conditions, including but not limited to sepsis, multiple organ dysfunction syndrome, and peripartu...
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 کاملComparison 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 کاملUse of central venous oxygen saturation to guide therapy.
The use of pulmonary artery catheters has diminished, so that other technologies are emerging. Central venous oxygen saturation measurement (ScvO₂) as a surrogate for mixed venous oxygen saturation measurement (SvO₂) is simple and clinically accessible. To maximize the clinical utility of ScvO₂ (or SvO₂) measurement, it is useful to review what the measurement means in a physiologic context,how...
متن کاملChallenges associated with central venous catheter placement and central venous oxygen saturation monitoring.
Patients with septic shock and respiratory failure often require hemodynamic monitoring in order to guide bedside management. This is particularly true of patients with dialysis-dependent chronic kidney disease, who may be less tolerant of large volume resuscitation than individuals with normal renal function. With the declining use of pulmonary artery catheters and the introduction of early go...
