Healthy Kidneys cleanse the blood and eliminate extra fluid in the form of urine. When your kidney does not function properly, it cannot remove waste products from the blood. Then dialysis is performed surgically where a device filters wastes, salts, and fluid from the blood. Usually, hemodialysis is advised in such cases.
In hemodialysis, a machine with a special filter called an artificial kidney or a dialyzer removes the wastes from the blood. Access is made to draw the blood from the blood vessels surgically in the arm. One side of the dialyzer, or filter, draws the blood and another side is used to wash fluid called dialysate. These 2 parts are separated by a thin membrane which allows smaller waste products in the blood to pass through them blocking the blood cells, proteins, and other large things to remain in the blood. Thus, smaller waste products like urea, creatinine, potassium, and extra fluids are washed eliminated from the blood.
Hemodialysis is performed in 3 different ways:
In-Centre hemodialysis: This is performed in a dialysis center with a nurse’s assistance. is a 4-hour procedure done 3 times?

Some patients prefer hemodialysis treatment at the comfort of their homes. The caretakers are trained to carry out dialysis carefully and taught to handle any issues that may arise. There are several ways, home dialysis is performed. Standard dialysis is performed 3 times per week for 3-4 hours in each session similar to in-center hemodialysis. In another way, dialysis is performed for a short duration of 2 hours but 5-7 times a week. Since dialysis is performed more frequently, only a small quantity of fluid has to be removed in each session.
This kind of hemodialysis can either be done at home or dialysis center. This procedure is done over 6 to 8 hours in the night while the patient is sleeping. Nocturnal hemodialysis can be performed 3 to 6 nights every week depending on how the patient responds. In a few cases, patients may have to opt for day and nocturnal hemodialysis depending on their medical conditions.
