Background In severe sepsis and septic shock, global tissue hypoxia is a key development preceding multi-organ failure and death. Objective Our aim was to find whether the initial low oxygen extraction ratio (OER) is related to the severity of organ dysfunction and to predict the in-hospital mortality in severe sepsis or septic shock patients. Methods This was a secondary analysis of 169 patients with severe sepsis or septic shock in an emergency department. We calculated OER with 1- central venous oxygen saturation (ScvO2)/arterial oxygen saturation and compared the data according to the level of OER (high > 0.3, 0.2).
