Treatment settings, such as the amount of solution to be infused and the length of
time the solution remains in the peritoneal cavity, are programmed on the cycler.
The cycler then automatically performs the treatment. In APD, the treatment
settings can be modified to meet the needs of each patient.
There are four (4) types of APD therapy:
Continuous Cycling Peritoneal Dialysis/Intermittent Peritoneal Dialysis
(CCPD/IPD)
Tidal Peritoneal Dialysis (TPD)
Hi-Dose Continuous Cycling Peritoneal Dialysis (Hi-Dose CCPD)
Hi-Dose Tidal Peritoneal Dialysis (Hi-Dose TPD)
See Section 1, Glossary for definitions of each of these therapies.
5.3 HomeChoice APD Systems Functions
The HomeChoice and HomeChoice PRO APD Systems perform peritoneal dialysis by
directing the flow of fluid between the solution bags, the cassette, your peritoneal
cavity, and your drain option.
Once you have connected all solution bags and your drain option, and have
connected yourself to the disposable set, you have created a fluid circuit. The
system manages your PD by the following methods:
With the cassette loaded in the cycler, the system is able to draw fluid into
the cassette chambers by opening and closing the correct combination of
valves on the cassette.
The system measures the fluid in the cassette chambers. It then opens and
closes the required valves on the cassette to move fluid to the correct
destination. This allows the system to deliver the programmed Fill
Volume to your peritoneal cavity with high accuracy.
The measurements taken during the Drain cycle allow the system to
calculate how much ultrafiltrate (UF) was removed from your peritoneal
cavity during each Drain cycle. These values are stored in the system so
that you can view them at the end of your therapy.
