Understanding peritoneal dialysis
Peritoneal dialysis treatment is so called, because the blood is filtered in the peritoneum – the membrane that lines the abdominal cavity.
The peritoneal cavity stores the dialysis fluid and the filtration takes place across the peritoneum. Toxins and excess fluid cross the peritoneal membrane during the prescribed dwell time.
A permanent tube, or catheter, is inserted into the peritoneal cavity. Through which, dialysis fluid is fed into the cavity and left to absorb the impurities from the blood. Later, the fluid is drained-off into a bag and replaced with fresh fluid.
This process, of filling and draining, can be done manually during the day. Or done automatically at night with a cycler. Either way you will need to feel capable and confident to handle the procedure.
