Which is the FDA Class II specialized indicator run daily in a dynamic air removal sterilizer?

The Bowie-Dick test is recognized as an FDA Class II specialized indicator specifically intended for use in dynamic air removal sterilizers. Its primary purpose is to ensure that air has been effectively removed from the sterilizer chamber and that steam has penetrated the load properly. This test typically involves a set of test packs that are placed within the sterilizer and subjected to the same conditions as a typical sterilization cycle.

This indicator effectively provides insight into the efficiency of the sterilization process, particularly in relation to air removal, which is critical for achieving proper sterilization in autoclaves that utilize a vacuum or pulsed pressure system. When the Bowie-Dick test is performed daily, it helps to confirm that the sterilizer is functioning correctly and that it can achieve the necessary conditions for sterilization, thereby safeguarding patient safety and compliance with regulatory standards.

In contrast, the steam indicator is used for other measures, while chemical indicators serve different purposes that do not specifically target dynamic air removal efficiencies like the Bowie-Dick test. Biological indicators are used to confirm the effectiveness of a sterilization cycle but are not specialized for daily checks of air removal in a sterilization process.
