Webthan systolic pressure variation, which had been previously evaluated (26, 27), is that pulse pressure, which is differential, is less directly inﬂuenced by the cyclic changes in intrathoracic pressure than systolic pressure. Accordingly, we showed that PPV was a better predictor of ﬂuid responsiveness than systolic pressure variation (24). WebJan 1, 2024 · This has led to the concept of assessing fluid responsiveness before infusing fluid. Pulse pressure variation (PPV), which quantifies the changes in arterial pulse pressure during mechanical ventilation, is one of the dynamic variables that can predict fluid responsiveness.
