When sterilizing an unwrapped, non-porous item in immediate use sterilization, what parameters must be met for gravity displacement steam?

For immediate use sterilization of unwrapped, non-porous items utilizing gravity displacement steam, the critical parameters must include both the correct temperature and exposure time. Specifically, the required exposure time for this method is 3 to 4 minutes at a minimum temperature of 270°F.

This process is designed for situations where items need to be sterilized quickly for immediate use, such as in a surgical setting. The short exposure time is effective in ensuring that microorganisms are eliminated efficiently under the specified conditions.

The choice reflecting 3-4 minutes aligns with established guidelines, ensuring that the sterilization process is both rapid and effective, making it vital for maintaining sterile conditions in surgical and clinical settings.
