Central venous oxygenation: when physiology explains apparent ...
2014年11月10日 · 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 …
Serial assessments of cardiac output and mixed venous oxygen …
2023年10月27日 · 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%). …
SvO2 to monitor resuscitation of septic patients: let's just …
2011年11月7日 · 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 …
Clinical review: use of venous oxygen saturations as a goal - a yet ...
2011年10月24日 · 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 …
High central venous oxygen saturation in the latter stages of septic ...
2011年7月26日 · 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) …
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
High mixed venous oxygen saturation levels do not exclude fluid ...
2011年7月26日 · Introduction The aim of this study was to determine whether the degree of fluid responsiveness in critically ill septic patients is related to baseline mixed venous oxygen saturation (SvO2) levels. We also sought to define whether fluid responsiveness would be less likely in the presence of a high SvO2 (>70%). Methods This observational study was …
Central venous oxygen saturation in septic shock - BioMed Central
2011年8月18日 · Shock therapy aims at increasing central venous oxygen saturation (ScvO2), which is a marker of inadequate oxygen delivery. In this issue of Critical Care, Textoris and colleagues challenge this notion by reporting that high levels of ScvO2 are associated with mortality in patients with septic shock. This is of obvious interest, but as their retrospective …
Clinical relevance of data from the pulmonary artery catheter
2006年11月27日 · 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) …
Optimizing PO2 during peripheral veno-arterial ECMO: a narrative …
2022年7月26日 · 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 …
