Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to assess the responsiveness of the standard minimally invasive hemodynamic monitors used in the operating room to known changes in the intravascular volume status that occur during blood removal and volume replacement with three different standard fluids used during ANH.
