peritoneal dialysis involves filling the peritoneal cavity with dialysate, allowing the fluid to dwell for a certain period, draining it out and then replacing it with fresh dialysate. The dwell time to achieve full equilibration between dialysate and plasma solute concentrations is approximately 4 hours. If the dwells are short, for example 1 to 2 hours, then the procedure is called Intermittent peritoneal dialysis (IPD). IPD is commonly performed in hospital using a machine (cycler) to do the exchanges *Intermittent peritoneal dialysis (IPD)* IPD alternates dialysis over various period (12-24 hours) with interdialytic phases lasting from 14 hours to several days according to the patient´s needs
