Bacterial/Viral Filter Use; Chemical/Biological Filter Use - ZOLL Z Vent Operator's Manual

Operating Environments
Warning! The Medical Control Officer and/or Incident Commander should determine which, if
any, external filter is used based on the potential hazard.
Warning! You must ensure that nothing blocks the inlet of the external filter; failure to do so could
prevent the patient from breathing and cause a ventilator failure.

Bacterial/Viral Filter Use

You can use Bacterial/Viral (B/V) filters in environments where the patient is at risk from cross
contamination of airborne pathogens. When used in accordance with the manufacturer's
instructions, these filters can help prevent inhalation of infectious matter. In dusty
environments, you can also use the B/V filters to prevent entrainment of particulate matter that
could affect the ventilator's pneumatic components. To use a bacterial/viral filter, insert the
filter's male 22 mm conical fitting into the Fresh Gas/Emergency Air Intake.
Warning! If filters have been exposed to biological matter, dispose of them following the Universal
Precaution procedures for your facility.

Chemical/Biological Filter Use

The ZOLL 731 Series Ventilator is designed to allow attachment of chemical/biological filter/
canister (type C2A1
Intake fitting allows for attachment of standard Rd 40 x 1/7 threads. A complete description of
this standard can be found in BS EN 148-1:1999 Respiratory protective devices - Threads for
face pieces.
1. A 3M C2A1 canister (3M St. Paul, MN) was used in our validation testing to represent the class of filters
generically known as C2A1 under the NSN number 4240-01-361-1319. These tests confirmed the
performance of the ventilator when operating with these devices as a class. Use of the 3M canister does not
constitute endorsement or recommendation of the 3M device. Use and selection of the appropriate filter
should always be under the direction of the Incident Commander.
