Automated peritoneal dialysis (APD)
Throughout APD, a machine known as a cycler does the exchanges. Every evening, the catheter is hooked up to the tubing of the cycler. It does a number of exchanges, shifting the dialysate out and in of the physique whereas the individual is asleep. APD is completed each evening and normally takes between eight to 10 hours.
