Onset phase: Kidney injury occurs.
Oliguric (anuric) phase: Urine output decreases from renal
tubule damage.
Diuretic phase: The kidneys try to heal and urine output
increases, but tubule scarring, and damage occurs. Recovery
phase: Tubular edema resolves, and renal function improves.
14. Know common findings of ARDS
(acute respiratory distress syndrome)
