Stroke Volume Variation

  • 301 Accesses

Abstract

Assessment of fluid responsiveness can be challenging. The primary goal of a fluid bolus is an increase in stroke volume (SV). However, repeated fluid challenges to assess volume responsiveness (VR) serve no benefit if your patient is on the flat portion of the Frank-Starling curve. Moreover, additional fluid could be harmful if it results in elevated atrial pressure and venous congestion.
