Mind the influence of arterial oxygen tension on central venous oxygen saturation
We read with great interest the study by Hernandez and colleagues published in Critical Care [1]. The study showed that central venous oxygen saturation (ScvO2) increased significantly in response to emergency intubation, and the authors suggested that the early normalization of ScvO2 after intubation might not be reliable to reflect successful resuscitation. However, they might have ignored th...
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 کاملValidity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content
Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...
متن کاملThe effect of breast milk odor on concentration percentage of oxygen saturation and respiratory rate in premature infants
Background: establishing a regular respiratory condition in the infants is one of the basic considerations in NICU. Newborns show noticeable breath alterations in response to even low concentrations of some fragrance. Aim: determining the effect of breast milk odor on oxygen saturation and respiratory rate in premature infants. Methods: In this four-group randomized clinical trial, 180 prematu...
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...
