WebJan 7, 2015 · Studies have shown that respiratory variations in stroke volume and its derivatives are affected by respiratory rate, resulting in limited ability to predict the response to fluids at high respiratory rate. 2 It has also been shown that pulse pressure variation (PPV), and hence SVV, cannot predict fluid responsiveness reliably in patients who … WebMar 28, 2024 · Introduction: Several studies have shown that maximizing stroke volume (or increasing it until a plateau is reached) by volume loading during high-risk surgery may improve post-operative outcome. This goal could be achieved simply by minimizing the variation in arterial pulse pressure (deltaPP) induced by mechanical ventilation.
