The Preparation of Dialysis Fluid
Inlet Water Requirements
The chemical and microbiological quality of the water used to prepare
fluids for dialysis is an important factor for achieving and maintaining
the proper quality of the dialysis fluid.
The quality of the water depends on the technical equipment for water
treatment. Further, proper maintenance of the water treatment system
and of the water distribution loop is essential.
The inlet water must comply with valid standards for water for dialysis;
see "Water supply" on page 9:11 in part 1 for more details.
Preparation of the Dialysis Fluid
The AK 96 dialysis machine prepares dialysis fluid from inlet water
and concentrates.
The dialysis fluid should be made from an acidic (A) concentrate and a
dry bicarbonate concentrate (such as the BiCart cartridge). It can also
be made from an acidic (A) concentrate and a liquid
bicarbonate (B)
concentrate or from an acetate concentrate. See "Concentrates" on
page 1:19 in part 1.
UFD- Ultrafiltered Dialysis Fluid (option)
The AK 96 dialysis machine can be equipped with a holder in which
an ultrafilter can be mounted. The ultrafilter purifies the dialysis fluid
from possible contamination by bacteria and endotoxins.
Ultrafilter - Frequency of Change
The ultrafilter used when
preparing Ultra Filtered Dialysis Fluid is to
be changed regularly depending on the primary fluid quality and the
desired final fluid quality. The results from microbiological controls
have to determine the
frequency of change. A frequency between once
a month and once every three months can be expected.
For instructions
on how to change the ultrafilter, see “Ultrafilter - How
tochange"onpage8:39inpart1.
