Final answer:
Dialysate is typically allowed to remain in the peritoneum for a dwell time of 4 to 6 hours during peritoneal dialysis sessions.
Step-by-step explanation:
The dialysate is allowed to remain in the peritoneum for a specific period during dialysis to allow for the efficient transfer of waste and excess water out of the blood and into the dialysate solution. Typically, during peritoneal dialysis, the dialysate remains in the peritoneum for about 4 to 6 hours, which is known as the dwell time.
However, this can vary depending on the patient's prescription and the modality of peritoneal dialysis being used (continuous ambulatory peritoneal dialysis (CAPD) or automated peritoneal dialysis (APD)). It's important to note that while a session can last 2–8 hours, the dwell time specifically refers to the length of time the dialysate is stationary within the peritoneum before it is drained and refreshed.
