A hemodialysis unit's dialysate solution tanks. Once purified water is mixed with dialysate (also called dialysis fluid) concentrate consisting of: sodium, potassium, calcium, magnesium and dextrose mixed in an acid solution; this solution is mixed with the purified water and a chemical buffer. This forms the dialysate solution, which contains ...
Dialysis is the process used to change the matrix of molecules in a sample by differentiating molecules by the classification of size. [6] [7] It relies on diffusion, which is the random, thermal movement of molecules in solution (Brownian motion) that leads to the net movement of molecules from an area of higher concentration to a lower concentration until equilibrium is reached.
Dialysis is an imperfect treatment to replace kidney function because it does not correct the compromised endocrine functions of the kidney. Dialysis treatments replace some of these functions through diffusion (waste removal) and ultrafiltration (fluid removal). [6] Dialysis uses highly purified (also known as "ultrapure") water. [7]
Aluminium toxicity is known to result from high levels of aluminium in water used to prepare dialysate; therefore, aluminium levels in water supplies used to prepare dialysate must be measured on a regular basis, especially in regions where aluminium is added to the water supply as well as areas with high aluminium concentrations in ground or ...
Peritoneal dialysis (PD) is a type of dialysis that uses the peritoneum in a person's abdomen as the membrane through which fluid and dissolved substances are exchanged with the blood. [ 1 ] [ 2 ] It is used to remove excess fluid, correct electrolyte problems , and remove toxins in those with kidney failure . [ 3 ]
Hemofiltration is sometimes used in combination with hemodialysis, when it is termed hemodiafiltration. Blood is pumped through the blood compartment of a high flux dialyzer, and a high rate of ultrafiltration is used, so there is a high rate of movement of water and solutes from blood to dialysate that must be replaced by substitution fluid that is infused directly into the blood line.
Renal replacement therapy includes dialysis (hemodialysis or peritoneal dialysis), hemofiltration, and hemodiafiltration, which are various ways of filtration of blood with or without machines. Renal replacement therapy also includes kidney transplantation , which is the ultimate form of replacement in that the old kidney is replaced by a donor ...
Electrodialysis, used to transport salt ions from one solution to another through an ion-exchange membrane under the influence of an applied electric potential. Kidney dialysis is the process of removing water, solutes and toxins from the blood of individuals with compromised kidney function, primary types of which are: Hemodialysis
