Web01. apr 2015. · Renal autoregulation clearly acts normally as a high-pass filter in adjusting afferent arteriolar diameter to limit changes in P GC caused by fluctuations in RPP. P GC has a pulse pressure of 7–10 mmHg which is roughly one-third of arterial BP pulsations (47, 148, 347). This demonstrates damping of the very rapid pulsations at heart rate ...

WebImpaired Renal Autoregulation Autoregulation normally occurs between systolic blood pressures of 80 and 150 mm Hg, and between these ranges, renal blood flow, glomerular pressures, and GFR are maintained. Below 80 mm Hg, this autoregulation fails, and ischemic injury may result. Webbetween the autoregulation of blood flow and the control of arterial pressure will be presented.
