During the conditioning stage of a sterilization process, it is crucial that air is effectively removed from the sterilizer chamber, and steam is introduced to create the necessary conditions for sterilization. This stage is essential in preparing the items for the subsequent sterilization cycle, ensuring that steam can penetrate effectively and uniformly throughout the load being sterilized.

Maintaining the right humidity and temperature during this phase is also vital, but the primary goal of conditioning is to ensure that air pockets are eliminated—this is why introducing steam is a critical step. This not only enhances the efficacy of the sterilization process but also helps in achieving the appropriate temperature and humidity levels needed for successful sterilization.

The other options do not reflect the correct process during the conditioning stage. For instance, the statement about temperature remaining constant overlooks the fact that specific temperature guidelines must be followed to ensure effective steam penetration. Claiming that devices are packed tightly disregards that items should be arranged to allow steam circulation. Lastly, the assertion about only using liquid agents is misleading, as sterilization can be achieved using a variety of methods, not just liquid agents, particularly in the context of steam sterilization.
