Post-Contaminated Environment Cleaning

If you have used the ZOLL Ventilator in an environment where it may have been exposed to
contamination from a hazardous materials accident, mass epidemic, or weapon of mass
destruction, we recommend that you follow these guidelines:
1. Always follow the decontamination procedures specified by the local Incident Command
Safety Officer.
2. You should clean and decontaminate the equipment as soon as possible after use. Personnel
should always wear the appropriate Personal Protective Equipment while decontaminating
equipment.
Review the cleaning instructions that we provide in the previous section.
3.
Since the potential amount of contaminants that the ventilator might be exposed to is so large,
4.
it is difficult to provide an appropriate cleaning method for each type of exposure. An
effective cleaning agent for one type of exposure may not be effective with another. Cleaning
and sterilizing practices may vary between institutions. We suggest that each facility have in
place a procedure for the cleaning and disinfection of its medical equipment and that these
procedures to consulted for further guidance.

Gas Intake Filters

The fresh gas intake (located on the right side of the ventilator) has a two stage filtering system:
an easily accessible foam filter protects a second disk filter. As we describe in Chapter 6,
"Operating Environments," additional filter protection may be necessary when operating the
unit in extreme environments.

Inspecting and Replacing the Foam Filter

When used in dusty environments, you should inspect and replace, if necessary, the unit's foam
filter (

Remove the filter using a pair of tweezers or similar tool. Examine the filter for dirt, lint, or
general wear. Replace the foam filter, if necessary. DO NOT attempt to clean the filter.
Caution Do not operate the compressor without a filter in place.

Inspecting and Replacing the Disk Filter

The Fresh Gas/Emergency Air Intake Disk Filter (
Foam Filter. This filter provides a second level of filtration to the ambient air that is delivered
to the patient. You must check this filter periodically and replace it if necessary. The ZOLL
Ventilator triggers an alarm when the combination of Foam Filter and Fresh Gas/Emergency
Air Intake Disk Filter become dirty. This alarm indicates that the unit is still able to deliver the
correct tidal volume but one or more of its filters needs replacement. You can visually inspect
the Fresh Gas/Emergency Air Intake Disk Filter after the Foam Filter is removed. If the filter
appears discolored, replaced it.
