WARNING Failure to use an air inlet filter may result in severe damage to the
internal components of the iVent
TM
201.
The air inlet filter must be replaced every 500 hours or every thirty days of
operation. See page 173 for air filter maintenance procedures.
BACTERIAL FILTER
A user-supplied bacterial filter prevents contamination of the patient circuit
components, and prevents bacteria, excessive humidity and liquids from entering
the iVent
TM
201.
WARNING Failure to use an adequate bacterial filter may cause severe damage
to internal pressure and flow sensors, which may result in ventilator
failure.
CHEMICAL, BIOLOGICAL, RADIOLOGICAL AND
NUCLEAR FILTER
In the event of environmental contamination by hazardous or toxic substances,
the air-inlet filter should be replaced with an optional CBRN canister. CBRN
canisters are designed for first-response protection against nuclear, toxic, or
biological particulate material and chemical vapors, gases, and mists/aerosols
and tear gas.
