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.
A kidney machine that purifies a person’s blood when the kidneys fail.
Process of removing toxic substances from blood with the aid of a synthetic semipermeable membrane.
A form of dialysis using an artificial machine to replace the kidney’s functions.
Procedure, used in toxic conditions and renal (kidney) failure, in which wastes and impurities are removed from the blood by a special machine. The blood is shunted to and from a dialyzer where, through diffusion and ultrafiltration, wastes are removed. Popularly known as artificial kidney.
Filtering of blood through an external machine that stands in for the kidneys; used in cases of renal failure and some toxic conditions.
A medical procedure that cleans and filters the blood by removing waste products, extra salt, and fluid from the blood through a dialysis machine.
A technique of removing waste materials or poisons from the blood using the principle of dialysis. Hemodialysis is performed on patients whose kidneys have ceased to function; the process takes place in an artificial kidney, or dialyzer. A stream of blood taken from an artery is circulated through the dialyzer on one side of a semipermeable membrane, while a solution of similar electrolytic composition to the patient’s blood circulates on the other side. Water and waste products from the patient’s blood filter through the membrane, whose pores are too small to allow passage of blood cells and proteins. The purified blood is then returned to the patient’s body through a vein.
A method of removing waste products or poisons from the circulating blood using the principle of dialysis. The procedure is used on patients with malfunctioning or nonfunctioning kidneys. It uses an artificial kidney, or dialyser, which restores blood to its normal state. The process has to be repeated, sometimes for many months or years, until a donor kidney is available for transplantation to replace the patient’s failing one.
Hemodialysis is one of the two methods of dialysis used to treat kidney failure. It involves the artificial filtration of the blood to remove waste and excess fluids from the body.
