What is Dialysis or Haemodialysis

Dialysis is an artificial process used to remove water and waste substances from the blood when the kidneys fail to function properly.
The word “HAEMO” refers to blood. Hemodialysis is a method for removing waste products such as potassium and urea, as well as free water from the blood when the kidneys are in renal failure.
The blood travels outside the body through tubing and passes through a filter of the dialysis machine.
The filter cleans the blood and the clean blood is returned to your body.

Working Principle of Dialysis

Dialysis works on the principles of the diffusion of solutes and ultrafiltration of fluid across a semipermeable membrane.
Diffusion describes a property of substances in water. Substances in water tend to move from an area of high concentration to an area of low concentration.

Approximately 1.5 liters of blood are filtered by a healthy person’s kidneys each day.
We could not live if waste products were not removed from our kidneys.
Without dialysis the amount of waste products in the blood would increase and eventually reach levels that would cause coma and death.

Cleanses the blood of accumulated waste products.
Removes the by-products of protein metabolism such as urea, creatinine, and uric acid.
Removes excessive fluids.
Maintains or restores the buffer system of the body.
