906-0731-01-05 Rev. C ZOLL Ventilator Operator’s Guide 7-3Post-Contaminated Environment CleaningIf you have used the ZOLL Ventilator in an environment where it may have been exposed tocontamination from a hazardous materials accident, mass epidemic, or weapon of massdestruction, we recommend that you follow these guidelines:1. Always follow the decontamination procedures specified by the local Incident CommandSafety Officer.2. You should clean and decontaminate the equipment as soon as possible after use. Personnelshould always wear the appropriate Personal Protective Equipment while decontaminatingequipment.3. Review the cleaning instructions that we provide in the previous section.4. Since the potential amount of contaminants that the ventilator might be exposed to is so large,it is difficult to provide an appropriate cleaning method for each type of exposure. Aneffective cleaning agent for one type of exposure may not be effective with another. Cleaningand sterilizing practices may vary between institutions. We suggest that each facility have inplace a procedure for the cleaning and disinfection of its medical equipment and that theseprocedures to consulted for further guidance.Gas Intake FiltersThe 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 theunit in extreme environments.Inspecting and Replacing the Foam FilterWhen used in dusty environments, you should inspect and replace, if necessary, the unit’s foamfilter (REF 465-0028-00).Remove the filter using a pair of tweezers or similar tool. Examine the filter for dirt, lint, orgeneral 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 FilterThe Fresh Gas/Emergency Air Intake Disk Filter (REF 465-0027-00) is located behind theFoam Filter. This filter provides a second level of filtration to the ambient air that is deliveredto the patient. You must check this filter periodically and replace it if necessary. The ZOLLVentilator triggers an alarm when the combination of Foam Filter and Fresh Gas/EmergencyAir Intake Disk Filter become dirty. This alarm indicates that the unit is still able to deliver thecorrect tidal volume but one or more of its filters needs replacement. You can visually inspectthe Fresh Gas/Emergency Air Intake Disk Filter after the Foam Filter is removed. If the filterappears discolored, replaced it.
