What devices typically undergo immediate use steam sterilization?

Immediate use steam sterilization (IUSS) is a process specifically reserved for instruments that are urgently needed in situations where no alternative sterilized items are available. This method is primarily utilized in emergency cases where time is critical, and it enables the prompt availability of sterile instruments for procedures that cannot be delayed.

Instruments required for urgent procedures are typically those that are necessary for life-saving interventions or rapid surgical responses. These instruments may not be able to undergo the standard sterilization processes due to time constraints, making IUSS a vital tool within the healthcare setting.

The other options do not align with the primary purpose of immediate use steam sterilization. Not all surgical instruments require this method, and IUSS is not meant for disposable items or non-critical items, as these can typically wait for a full sterilization cycle. Thus, the accurate understanding of IUSS includes recognizing its application in urgent scenarios to ensure patient safety and procedural efficacy.
