Respiratory Variation in Central Venous Oxygen Saturation Predicts Volume Responsiveness in Hemodynamically Unstable Patients Under Mechanical Ventilation : a Prospective Cohort Study

Vascular filling is the main treatment of hypovolemia. Hypovolemia diagnosis can be difficult in some situations and need to be confirmed with other investigations. Venous oxymetry based on the ScvO2 values represent a valuable way to predict responsivness to fluid filling maneuver in patients with hemodynamic instability.
