ing of IUSS cycles, readers should now refer to Section 13.7.2, Routine monitoring of sterilizers larger than 2 cubic feet. Qualifica- tion testing of dynamic-air-removal IUSS cycles is done by running a commercial BI PCD in an empty chamber in three consecutive cycles, followed by three con- secutive Bowie-Dick tests.
routine bowie-dick testing For dynamic-air-removal sterilizers, AAMI ST79 continues to recommend that: “A Bowie-Dick (Type 2 CI) test should be performed each day the sterilizer is used, before the first processed load.”(Section 13.7.6.1) As with BI PCDs, note that while facilities may assemble their own towel test packs, the standard now recommends the use of commercially available preas- sembled Bowie-Dick test packs.(Section 13.7.6.2)
Summary
All health care facilities that utilize steam sterilization should have a copy of this lat- est edition of ANSI/AAMI ST79 on hand and accessible to staff. The publication of this new edition provides a great oppor- tunity to revisit your facility’s policy and procedures to ensure they are aligned with current guidance. In particular, policies that may need refreshing include: • with your facilities engineer, alignment of sterile processing area temperature and humidity operating parameters with the applicable ASHRAE 170 standard and a plan on who will monitor these parameters
• loaners • frequency of testing mechanical cleaning equipment
• the use of internal chemical indicators • the monitoring of pre-vacuum sterilizers used for IUSS HPN
