Prerenal Acute Kidney Injury (AKI) is characterized by conditions that decrease blood flow to the kidneys. The key criteria to watch for include: low blood pressure, reduced blood volume (due to bleeding, dehydration, or severe infection), and heart failure. Early signs are often elevated blood urea nitrogen (BUN) and creatinine levels without damage to the kidney itself. Proper hydration and prompt treatment of underlying conditions are crucial to prevent progression.
