Renal Resistive Index Responsiveness to a Mean Arterial Pressure Test As a Guide for Mean Arterial Pressure Target in the Early Phase of Septic Shock: A Physiological Study.
OBJECTIVES Guidelines recommend targeting a mean arterial pressure (MAP) greater than or equal to 65 mm Hg in septic shock. Although experts advocate for individualized targets, no validated bedside tool exists. An increased renal resistive index (RRI) is associated with acute kidney injury, and increasing MAP can redu...
