Types of dialysis

There are two main types of dialysis, hemodialysis and peritoneal dialysis, and several subtypes.

• In hemodialysis, also known as artificial kidney, the patient's blood is passed through a tube to a semipermeable membrane (dialyser) that filters out waste products. The cleansed blood is then returned back to the body. The procedure is monitored by a machine, which provides also the dialysis fluid, mixing it from a concentrate and water. Depending on where the treatment is done, dialysis is either:
• Hospital Hemodialysis
• Satellite Hemodialysis (a specialized unit outside a hospital, but managed by professional staff)
• Home Hemodialysis
• In peritoneal dialysis, a special solution is run through a tube into the peritoneal cavity, the abdominal body cavity around the intestine. The fluid is left there for a while to absorb waste products, and then removed through the tube. Subtypes of peritoneal dialysis are:
• Continous Ambulatory Peritoneal Dialysis (CAPD)
• Continous Cyclic Peritoneal Dialysis (CCPD)
• Intermittent Peritoneal Dialysis (IPD)
• Nocturnal Intermittent Peritoneal Dialysis (NIPD)
