Techniques for Assessment of Intravascular Volume in Critically Ill Patients

From the Division of Pulmonary and Critical Care Medicine, Eastern Virginia Medical School, Norfolk, Virginia, paul{at}marikonline.org

Fluid replacement is considered the cornerstone of resuscitation in the ICU. However, only about 50% of critically ill hemodynamically unstable patients are fluid responsive; furthermore, both under-resuscitation and overzealous fluid administration adversely affect outcome Consequently, the resuscitation of critically ill patients requires an accurate assessment of the patients’ intravascular volume status and their volume responsiveness. This paper reviews the evolution and accuracy of methods for assessing fluid responsiveness in critically ill patients.

Key Words: CVP • PAOP • pulse pressure variation • stroke volume variation • pulse contour analysis • heart— lung interactions • fluid responsiveness • preload • stroke volume • fluid therapy • hemodynamic monitoring • critical care • echocardiography • ICU
