6.15.2 Water trap and sampling line
The water trap protects the internal gas
analyzer from humidity, bacterial
contamination, etc. It consists of a filter
housing and a water container.
The sampling line is not reusable and must be
replaced between patients or when the
cleanliness of the tubing or connector is
compromised.
To maintain measurement accuracy:
• perform a System checkout before
connecting the system to the patient
• do not connect several sampling lines in
order to extend the line’s reach.
If the water trap is poorly fastened or not
installed, the gas analyzer’s internal pump is
disabled and there is no flow through the
measuring system.
The water trap, sampling line (marked 'gas
sample') and connectors are all parts of a
system optimized for the gas analyzer. The
time delay of gas data and waveforms
displayed on the touch screen is dependant
on the length and inner diameter of the
sampling line. The use of kinked or damaged
sampling lines, non-approved brands, extra
connectors or extension lines may all severely
distort the displayed waveforms and possibly
misguide the user.
WARNINGS!
• If a broken water trap has been used
during operation, the gas analyzer might
be contaminated and damaged. If this is
the case, take the anesthesia system out
of operation and contact a service
technician trained and authorized by
MAQUET.
• Do not connect tubing other than gas
sampling lines to the water trap, even
though other tubing (e.g. IV lines) might
fit the connector on the trap.
CAUTION: Always use accessories
approved by MAQUET. Other accessories
may impair the measurements, affect
accuracy, and result in slower response
times.
