Fluid overload is deleterious in critically ill patients. It can lead to venous congestion, thereby increasing venous pressure, theoretically increasing the backpressure, and thereby reducing renal blood flow. Venous congestion thus can be an important contributor to acute kidney injury (AKI), with no validated tools to objectively identify venous congestion bedside.
