Air Removal Bowie-Dick Type Tests

Procedures for Use

• Test sterilizer once a day.
• Test at the beginning of each day. A shortened cycle should be used to preheat the system (i.e. omit the drying phase). If the sterilizer is in continual use, then testing can be performed at any time, but it should be tested at the same time every day.
• Place the pack on the bottom rack in the front section of the sterilizer, near the door and over the drain.
• The test is most accurate when nothing else is in the chamber, so do not use this cycle to sterilize items or packs. Other items in this cycle may invalidate the test.
• Run a pre-vacuum cycle following the parameters printed on the indicator instructions. You may eliminate the drying phase to save time without affecting the test.
• After the cycle is complete, remove the pack and open to examine the indicator sheet. CAUTION! Test pack may still be hot so use caution when handling to avoid injury.
• Record the necessary information on the sheet (or in a log book) and store for your records.
• The filter paper pack can be discarded into a paper recycle bin.

Interpreting the Test Results

A FAIL is indicated by a lighter color in the center of the pattern than around the edges — failure of the pattern to change completely to black. A PASS is obvious by a uniform black color over the entire pattern of the indicator sheet.
