Photograph of a man undergoing continuous ambulatory peritoneal dialysis, showing the infusion of dialysis fluid from a plastic bag directly into his peritoneal cavity via a plastic catheter. The aims of both peritoneal and haemodialysis (performed on a kidney machine) are to remove waste products from body fluids of a person whose kidneys' function insufficiently. In both cases the principles of dialysis are identical; waste solutes diffuse across a semipermeable membrane (in this case the peritoneal membrane) towards the lower solute concentrations of the dialysis fluid.
