14. Filter Systems
IIt is recommended that bacteria filters are
fitted in the fresh gas supply and on the
patient side of the exhalation block.
The filters reduce the possibility of infection
to the patient and contamination of the
ventilator from secretions or fluids in the
breathing circuits that could accidentally
enter the ventilators gas ports.
It is recommended that a silencer be fitted
on the exhaust side of the exhalation block,
this helps to reduce the noise level of the
system.
The SLE2000 can be used without bacterial filters in place, but the user must take
extra care in not allowing secretions or fluids to enter the ventilators gas ports.

14.2.1 Precautions when using bacterial filter N2587
The user should be aware that any occlusion of the filter increases the resistance to
airflow, resulting in increased or erratic airway pressures. Airway pressures should be
monitored during use and the filter changed if found to be contaminated in any way.
When using humidification the filter should be checked regularly for signs of water
build up which could cause occlusion.
