25. 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.
