12.1 General information
MAQUET recommends methods that have
been validated using the specified equipment
and procedures outlined in this manual. Other
methods may work but are not covered by the
warranty unless MAQUET has given written
permission.
As cleaning practices vary widely among
healthcare institutions, it is not possible for
MAQUET to specify particular practices that
will meet all needs, or to be responsible for
the effectiveness of cleaning procedures
carried out in the patient care setting.
When the accessories and/or auxiliary
equipment are not covered by the MAQUET
CE mark on the anesthesia system, refer to
cleaning instructions found in the equipment's
user documentation.
CAUTION: The system must not be
disassembled further than described in this
chapter 'Routine cleaning and
maintenance'.
12.2 Hygiene
The carbon dioxide absorbent has a potent
cidal effect on microorganisms and only a low
number of resistant spores pass through the
absorber. Studies strongly suggest that
patients rarely contaminate the absorber with
significant levels of bacteria/viruses
21
. The
bactericidal effect will however not be in effect
if the absorber is bypassed.
MAQUET recommends that a bacterial/viral
filter is always connected to the expiratory
connection on the patient cassette. This will
minimize the risk of cross-contamination.
If possible, cleaning should be performed
immediately after use and always before
disinfection/autoclaving. Blood or other
residues should not be allowed to dry onto
the devices.
Water quality affects cleaning/disinfection.
MAQUET recommends using deionized water
for this purpose. The water quality must never
be less than drinking water quality.
Follow the recommendations regarding
softening of water provided by the
manufacturer of the washer disinfector.
All personnel should be aware of the risk of
parts being contaminated when disassembling
and cleaning the system.
All disposable parts must be discarded
according to hospital routines and in an
environmentally safe way.
