oliguria Significantly reduced URINEproduction
that occurs as a consequence of RENAL FAILURE,
DEHYDRATION, hemorrhage (massive BLOODloss), or
SHOCK. Normal adult urinary output is 1500 milli-
liters to 3000 milliliters per day. In oliguria urinary
output is 500 ml per day or less. Oliguria indicates
that the KIDNEYSare not receiving enough blood or
are not functioning to filter the blood. Unless
urine output increases, toxins will accumulate in
the blood and the circumstance may become life-
threatening.
