WitrynaA growing body of evidence suggest that tissue oxygen extraction may be impaired in adult respiratory distress syndrome (ARDS) and sepsis. In these syndromes the minimum oxygen delivery needed to maintain a normal oxygen uptake appears to be increased, as tissues become hypoxic despite high levels of delivery. However, controversy …
