27. Bacterial Filters
It is recommended that bacterial 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.
The ventilator 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.

Cautions: When Using Bacterial Filter
N2587/000/001
The user should be aware that any occlusion
(ingress of H
2
O) 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.
The filter must be changed every 24 hours, or
when there is evidence of water in the filter.
