How Does Kidney Dialysis Work?
Kidney dialysis removes the waste and fluid that the kidneys can no longer remove from the body. Kidney dialysis also aims to maintain the body's balance by correcting the levels of various toxic substances in the blood. Without dialysis, all patients with complete renal failure become susceptible to death due to accumulation of toxins in the bloodstream.
Foundations of dialysis
There are two main types of dialysis: peritoneal dialysis and renal dialysis. Whatever type of treatment is chosen, dialysis goals are very similar, as dialysis is designed to replace many kidney functions. This treatment should: Remove waste, remove excess fluid, and balance the amount of chemicals (electrolytes) and other substances in the body. Effective dialysis requires: a semi-permeable membrane, blood supply, dialysis means, and a way to remove excess fluid.

Semi-thin-acting membranes
In dialysis, this membrane separates the blood from the dialysis fluid. Some materials are allowed to pass without other materials through it. Waste, water, electrolytes and other substances can also be removed from the blood into the dialysis fluid (sometimes in the other direction) through a process called "propagation". The movement of waste and other materials depends on the permeability of the membrane, the size and composition of the various substances, the compensation of the dialysis fluid, and the amount of blood supply of the membrane.
Blood supply
The better the blood supply of the membrane, the more effective treatment with dialysis. In dialysis, blood supply can be controlled by dialysis.
Dialysis fluid
In both dialysis methods, the dialysis fluid allows removal of waste from the blood. Moreover, it contains substances that help to correct the imbalance that occurs as a result of kidney failure.
Remove liquids
Fluid Removal Fluids are removed by very different processes in dialysis which are done by blood versus peritoneal dialysis. In hemodialysis which is by blood, the dialysis device uses the pressure to pull the fluid across the membrane from the blood to the dialysis fluid. In peritoneal dialysis, glucose is used in the detergent. This procedure urges excess fluid to move out of the blood towards the dialysis fluid until it is discharged regularly.
The goal of renal dialysis
Whatever type of dialysis is used, the goal is to remove waste, remove excess fluid, correct imbalances in electrolytes, and correct pH in the body.>quote
