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). WebAs pulse pressure rises above the normal of 40 mmHg, the risk of problems with your heart and blood vessels goes up, even with small increases. Pulse pressures of 50 mmHg or more can increase your risk of heart disease, heart rhythm disorders, stroke and more.
