Continuous ambulatory peritoneal dialysis (CAPD) is a form of dialysis which happens throughout the day/night, in which the person drains and exchanges their own fluid. 

During CAPD, dialysis fluid is left in the peritoneal cavity for 4-6 hours to allow waste products from the blood to accumulate. The fluid is then drained out. Fluid can be left overnight.

The other form of peritoneal dialysis is APD.

CAPD is an example of RRT.
