- Central venous oxygenation: when physiology explains apparent . . .
Central venous oxygen saturation (ScvO2) >70% or mixed venous oxygen saturation (SvO2) >65% is recommended for both septic and non-septic patients Although it is the task of experts to suggest clear and simple guidelines, there is a risk of reducing critical care to these simple recommendations This article reviews the basic physiological and pathological features as well as the metrological
- Serial assessments of cardiac output and mixed venous oxygen saturation . . .
Aim To assess the association with outcomes of cardiac index (CI) and mixed venous oxygen saturation (SvO2) in comatose patients resuscitated from out-of-hospital cardiac arrest (OHCA) Methods In the cohort study of 789 patients included in the “BOX”-trial, 565 (77%) patients were included in this hemodynamic substudy (age 62 ± 13 years, male sex 81%) Pulmonary artery catheters were
- SvO2 to monitor resuscitation of septic patients: lets just understand . . .
Real-time monitoring of mixed venous oxygen blood saturation (SvO2) or of central venous oxygen blood saturation is often used during resuscitation of septic shock However, the meaning of these parameters is far from straightforward In the present commentary, we emphasize that SvO2 - a global marker of tissue oxygen balance - can never be simplistically used as a marker of preload
- Clinical review: use of venous oxygen saturations as a goal - a yet . . .
Shock is defined as global tissue hypoxia secondary to an imbalance between systemic oxygen delivery and oxygen demand Venous oxygen saturations represent this relationship between oxygen delivery and oxygen demand and can therefore be used as an additional parameter to detect an impaired cardiorespiratory reserve Before appropriate use of venous oxygen saturations, however, one should be
- High central venous oxygen saturation in the latter stages of septic . . .
Introduction Current guidelines recommend maintaining central venous oxygen saturation (ScvO2) higher than 70% in patients with severe sepsis and septic shock As high levels of ScvO2 may reflect an inadequate use of oxygen, our aim was to evaluate the relation between maximal ScvO2 levels (ScvO2max ) and survival among intensive care unit (ICU) patients with septic shock Methods We
- Serial assessments of cardiac output and mixed venous oxygen saturation . . .
CI < median with SvO2 > median was present in 222 (39%), and low SvO2 with CI < median was present in 59 (11%) Spline analysis indicated that SvO2 value < 55% was associated with poor outcome Low CI at admission was not signicantly associated with mortality in multivariable analysis (p = 0 14) SvO2 was signicantly inversely
- Optimizing PO2 during peripheral veno-arterial ECMO: a narrative review . . .
During refractory cardiogenic shock and cardiac arrest, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is used to restore a circulatory output However, it also impacts significantly arterial oxygenation Recent guidelines of the Extracorporeal Life Support Organization (ELSO) recommend targeting postoxygenator partial pressure of oxygen (PPOSTO2) around 150 mmHg In this
- Clinical relevance of data from the pulmonary artery catheter
The usefulness of parameters measured using the pulmonary artery catheter has been challenged because no benefit in patient outcome has been observed in clinical trials However, technological advances have been made, including continuous measurement of cardiac output (CO), mixed venous saturation (SvO2), and right ventricle end-diastolic volume (CEDV) have been made Pulmonary artery
