The kidneys are responsible for filtering the blood, eliminating byproducts through the urine, eliminating excess water in the body, regulating electrolytes, producing erythropoietin which is responsible for red blood cell production, and regulating Vitamin D which is needed for calcium absorption. [5], AKI recovery can be classified into three stages 1–3 on the basis of the inverse of the AKI KDIGO serum creatinine criteria.

Inotropes – A drug which increases the blood pressure and enhances the heart contractility is given to patients with low blood pressure. If low blood pressure persists despite providing a person with adequate amounts of intravenous fluid, medications that increase blood pressure (vasopressors) such as norepinephrine and in certain circumstances medications that improve the heart's ability to pump (known as inotropes) such as dobutamine may be given to improve blood flow to the kidney.
