Peritoneal Dialysis (PD)
A form of dialysis that uses the lining of your abdomen, called the peritoneal
membrane, as a filter to remove waste products from your body.
A tube known as a catheter is surgically placed through the wall of your
abdomen. Dialysis solution flows from a bag through the catheter and into the
peritoneal cavity. Waste products and excess fluids from your body pass from
the blood through the peritoneal membrane and into the dialysis solution. The
dialysis solution, now filled with waste, is then drained from the peritoneal
cavity. This cycle may be performed multiple times.
Peritoneal dialysis can be performed with or without a mechanical device. See
also Automated Peritoneal Dialysis (APD).
Peritoneal Membrane
The layer of tissue that lines your abdominal cavity. A membrane can act as a
filter, allowing some particles to pass from one part of the body to another
while not allowing others to pass. The peritoneal membrane is used as a filter
during peritoneal dialysis.
Peritonitis
Inflammation of the peritoneal membrane, usually caused by infection.
Phase
A part of a cycle or an exchange. Each exchange is divided into three phases: a
Fill phase, a Dwell phase, and a Drain phase.
Positional Drainer
A patient who may increase Drain Volume by changing his/her position, or
who drains best in one position.
Priming
To prepare for therapy, priming is the process the system uses to fill all tubing
lines of the disposable set with solution. Priming removes air from the system.
