Question: 1 / 400

What is the typical maximum exchange volume used in automated peritoneal dialysis?

1 liter

2-3 liters

In automated peritoneal dialysis (APD), the typical maximum exchange volume is generally in the range of 2 to 3 liters for each exchange cycle. This volume is optimal for effectively removing waste products from the blood while minimizing discomfort for the patient. Utilizing this volume allows for adequate filling of the peritoneal cavity without causing excessive pressure or discomfort, ensuring efficient diffusion of solutes and ultrafiltration.

The choice of 2-3 liters also aligns with clinical practices and studies that have established this range as standard. It balances the need for adequate dialysis with patient comfort and the physiological limits of the peritoneum. Choosing volumes outside this range may not effectively support adequate dialysis or could potentially compromise patient tolerance during the procedure.
