Continuous ambulatory peritoneal dialysis therapy for patients with end stage renal disease

CAPD is a method of dialysis that uses the patient's own peritoneal membrane. The semipermeable membrane that lines the abdominal organs and cavity selectively allows the passage of waste products, electrolytes, and fluids. Hemodialysis is an extracorporeal process whereby the patient's blood is withdrawn through a percutaneous needle inserted into a blood vessel. In hemodialysis, the operating principle is a cellophane membrane placed between the patient's blood and wash solution.
