An extended aeration cycle is required for items sterilized in which sterilization process?

The correct answer pertains to the fact that ozone sterilization requires an extended aeration cycle for items that have been sterilized using this method. Ozone is a powerful oxidizing agent that can leave residues on instruments after the sterilization process is complete. This residue can be harmful if not adequately removed before the items are put back into use.

The aeration process for ozone sterilization allows the ozone gas to dissipate from the items being sterilized, thereby ensuring that any lingering ozone is eliminated and that the instruments are safe for handling and use. This essential step protects both patients and healthcare workers from potential ozone-related health hazards.

In contrast, other sterilization methods like steam, ethylene oxide, and dry heat have their specific requirements but do not necessitate the same extended aeration process as ozone does. For example, steam sterilization is efficient and leaves no harmful residues, while ethylene oxide does require aeration, but not as extended as ozone treatment, and dry heat sterilization also efficiently eliminates contaminants without such concerns.
