Maintenance - The Flow Path
The Flow Path
The maintenance of the fl ow path with regard to cleaning and
decalci fi cation is important, in order to maintain the speci fi ed
performance of the machine.
Cleaning
Fats, proteins and organic material originating from the patient may
deposit down stream of the dialyzer. The number of treatments and the
setting of parameters will in fl uence the amount of deposits downstream
of the dialyzer. A general guideline for the frequency of cleaning
with CleanCart-C cartridge and sodium hypochlorite (alternatively
CleanCart-A cartridge) is described in the introductory part of this
chapter ("Schedule for Hygiene and Maintenance" on page 8:6).
An increased level of cleaning may be necessary, depending on the
conditions described above. It must be noted that a lower frequency
may be suf fi cient to maintain the system.
Decalcification
Calcium-carbonate may deposit in the fl ow path. The requirements
for decalci fi cation vary depending on elements as water quality, type
of concentrate and bicarbonate settings. A general guideline for the
frequency of decalci fi cation with CleanCart-C cartridge or liquid citric
acid is described in the introductory part of this chapter ("Schedule
for Hygiene and Maintenance" on page 8:6). An increased level
of decalci fi cation may be necessary, depending on the conditions
described above. It must be noted that a lower frequency may be
suf fi cient to maintain the system.
Note
•
Incorrect cleaning of the UF cell may be a contributing factor
for increased inaccuracy of the UF system. If any deviations in
UF accuracy should occur, it is recommended to use sodium
hypochlorite weekly.
•
In order to enable the cleaning agents to remove fats,
proteins etc. ef fi ciently, cleaning should be carried out after
decalci fi cation.
