Elevated venous pressures decrease renal function

Why Venous Congestion

easily adapts to wide changes in arterial pressure (aka perfusion pressure) to maintain filtration

does NOT adapt to even small changes in venous pressures (aka venous congestion)

When the kidneys fail, the patient fails.

Keeping the kidneys healthy is a vital clinical goal.
