Clinical Trial Summary

The objective of fluid challenge is to increase oxygen delivery (DO2) in order to improve/restore tissue oxygen consumption (VO2). However the fluid challenge volume to administer stills in debate, some studies recommend to administer 250 mL. Previous studies suggested that 500 mL of fluid challenge administration may improve cardiac output and oxygen delivery. The relation between the amount of fluid expansion and oxygen delivery and oxygen consumption was not yet been studied in a randomized study in critical care patients. This is the purpose of this study.
