Performance of Non-Invasive Monitors During ANH

April 26, 2022 updated by: University of California, Davis

The Evaluation of Minimally Invasive Hemodynamic Monitors for the Assessment of Volume Responsiveness to Various Standard Replacement Fluids During Acute Normovolemic Hemodilution

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.
