WebJul 10, 2024 · stroke volume variation (SVV), a surrogate of PPV, is a useful and reliable dynamic measurement that aids in predicting a patient’s response to a fluid challenge.14,15 These studies infer that dynamic parameters such as SPV, PPV, and SVV are better predictors of fluid status than WebWesseling et al.27described a method to predict aortic flow, stroke volume variation (SVV) and, therefore, fluid responsiveness, using APWA. The Vigileo, FloTrac device (Edwards Lifesciences, Irvine, CA) utilizes algorithms to determine SVV, from standard deviations of the pulse pressure.
