Haemodialysis
Haemodialysis
Haemodialysis (pronounced: hee-mo-die-uh-luh-sis), also spelled hemodialysis, is a medical procedure used to remove waste products and excess fluid from the blood when the kidneys are not functioning properly.
Etymology
The term "haemodialysis" comes from the Greek words "haima" (blood) and "dialysis" (dissolution, dialysis).
Procedure
Haemodialysis involves diverting blood to a machine, known as a dialyser, where it is cleaned before being returned to the body. This process is usually carried out three times a week and each session lasts for about four hours.
