Fitting The Breathing Circuit And The Filters - Dräger Perseus A500 Instructions For Use Manual

Assembly and preparation

Fitting the breathing circuit and the filters

WARNING
Risk due to particles and dust
In order to protect the patient from particles
and dust, a filter must be used between the
inspiratory limb of the breathing system and
the patient.
Use a patient-side filter or a filter at the
inspiratory port.
WARNING
Risk of infection
The breathing system may be contaminated
with infectious agents/pathogens. This may
have the following causes:
– No bacteria filters have been used at the
Y-piece or at the expiratory port.
– The breathing system is being used for
the first time.
Perform the following steps:
– Reprocess the breathing system before
first use.
– Reprocess the breathing system if
necessary.
– Carry out the reprocessing as described
in the reprocessing instructions supplied
with the product.
– To prevent future contamination, use
bacteria filters close to the patient.
Perseus can be used with Infinity ID breathing
hoses or conventional breathing hoses. If no
leakage test has yet been performed after
switching on the system, hose compliance and
hose resistance will automatically be adopted
when Infinity ID breathing hoses are connected.

WARNING
Risk due to occluded components in the
breathing circuit
If filters, hoses, or endotracheal tubes are
occluded and sample gas is being taken from
between the patient and the occluded
component, the sample gas flow may lead
immediately to negative pressure in the
lungs.
Ensure the following when ventilating
pediatric patients and neonates:
– When fine pored filters are used, do not
connect the sample line between the tube
and the filter.
– When no filters but only an HME is in use,
set the alarm limits for MV low and Paw
high to values that are suitable for this
patient so that an incipient occlusion can
be detected.
NOTE
When applying tidal volumes in the range of the
maximum or minimum values indicated for each
patient category, use the smaller breathing bag
and the smaller breathing circuit.
NOTE
In order to make use of the functionality of the
Infinity ID breathing circuit, dispense with the
inspiratory and expiratory microbial filters and fit
the Y-piece with a filter instead. In cases which
preclude use of a microbial filter at the Y-piece,
the ID functionality of the Infinity ID breathing
hoses cannot be used.
