Pre-vacuum steam sterilizers depend on one
or more pressure and vacuum excursions at the beginning of the cycle
to remove air. This method of operation results in shorter cycle
times for wrapped items because of the rapid removal of air from the
chamber and the load by the vacuum system and because of the usually
higher operating temperature (132–135°C [270–275°F]; 141–144°C
[285–291°F]).Eliminating air-pockets is critical to
steam penetration in all areas of the sterilizer chamber. This type
of sterilizer generally provides for shorter exposure time and
accelerated drying of fabric loads by pulling a further vacuum at
the end of the sterilizing cycle.
A Bowie-Dick diagnostic test is to be used before the first
processed load of each day. It is a sensitive and rapid means of
detecting air leaks, or inadequate air removal or inadequate steam
penetration. Insufficient air removal in a pre-vacuum cycle will
leave air-pockets, affecting the lethality of the sterilizer cycle,
causing non-sterile instruments and/or supplies.

Bowie-Dick Test
Packs should be used daily to evaluate the
performance of air-removal (vacuum) system of
dynamic pre-vacuum type sterilizers. Available
as test cards or preassembled test packs.
Internal CI’s should be used within
each pouch or package, tray, or container. Class 5
Integrators should be used in conjunction with
physical monitoring and biological indicator
testing for verifying the efficacy of a
sterilization system. (See AAMI ST79:2006)
Recordkeeping is a must for all
sterile processing departments. This ensures
accountability and allows operators to trace
errors to their source. Tips on sterilizer
maintenance and technical advice are included with
each book.
Our easy peel-and-seal
sterilization pouches work with Steam, Chemical Vapor, and
Ethylene Oxide Gas sterilization procedures.
