Types of Peritoneal Dialysis
1. Continuous Ambulatory Peritoneal Dialysis: In CAPD dialysis solution is constantly present in the abdomen, typically being exchanged four to fives times per day, 7 days per week. The dialysis fluid is exchanged manually by the patient using the force of gravity to drain and fill the abdomen.

2. Automated Peritoneal Dialysis: In APD a cycler machine automatically exchanges fluid into and out of the abdomen for the patient. The cycler draws dialysis solution from larger bags (usually 5 L), which it warms to the desired temperature. The patient usually spends between 8 and 10 hours a night on the cycler, disconnects from the cycler in the morning after a final fill is delivered, and then is free to go about daily activities.

3. Intermittent Peritoneal Dialysis: IPD is a form of PD that is usually performed in a hospital or in a dialysis center. It is usually reserved for patients with acute renal failure or end-stage renal failure and sometimes for patients immediately after catheter placement who are uremic and need more urgent dialysis.

Not all patients’ peritoneal membranes transport solute at the same rate. In clinical practice, a patient’s peritoneal membrane transport characteristics can be determined by measuring the creatinine equilibration curve and the glucose absorption curve during a standardized peritoneal equilibration test (PET). Patients are classified principally into one of four transport categories: high, high-average, low-average, and low. High transporters tend to do better on regimens that have frequent, short duration dwells, such as APD, whereas low transporters tend to do better on regimens with longer duration dwells, such as CAPD. Average transporters are generally able to do well on a variety of PD regimens.
