Acute kidney failure is a type of kidney failure that occurs when the kidneys suddenly lose their functions and become incapable of filtering wastes products from the blood. The chance of acquiring AKF is greater if the patient is already hospitalized. In addition, AKF develops quickly and require intensive treatment. On the other hand, the patients could recover normal renal function if their health are good. AKF is characterized by drowsiness, swelling, and shortness of breath. However, sometimes AKF does not appear any signs or symptoms. AKF has four phases which are the onset phase, the oliguric phase, the diuretic phase, and finally the recovery phase.

The first phase which called onset phase occurs as a result of a reduce in the blood equipping to the kidney. Also, the onset phase could be triggered by burns, fluid loss, and diabetes insipidus. According to the ANA, “in the onset phase the renal blood flow of kidney is 25% of normal.” [1] Furthermore, the tissue oxygenation is also 25% of normal condition, and the urine output is below 0.5 ml/kg/hour. The duration for the onset phase endures for hours to days. The next phase is oliguric –also called anuric phase- happens when the level of blood urea nitrogen (BUN) and creatinine are increased. Moreover, oliguric phase decreases the amount of urine to less than 400 ml/day. Also, oliguric phase affects the electrolyte disturbance, acidosis, and fluid overload which lead to lose the capacity of the kidneys to excrete water. In this phase, uremic symptoms first appear and life-threating conditions develop. This phase can continue for eight to fourteen days or longer, and the duration depends on nature of acute kidney failure and dialysis …show more content…
In the onset phase, there is not enough blood in the kidneys, therefore, it affects the blood flow, the tissue oxygenation, and the urine output. The oliguric phase happens due to increase in the level of blood urea nitrogen and creatinine. Moreover, the symptoms start to appear and the condition evolves. Next, when the causes of acute renal failure have corrected, that means the diuretic phase presents. Finally, the kidneys will have recovered its functions in the recovery
