How is cycle time defined in a sterilization process?

• A. Time taken for pre-cleaning
• B. Total elapsed time from activation to completion
• C. Time required for drying sterilized instruments
• D. Time spent in transport between locations

Answer: (B)

Cycle time in a sterilization process refers to the total elapsed time from the moment the sterilization equipment is activated until the process is fully completed. This includes all stages of the sterilization cycle, such as the different phases depending on the method used—like the exposure, sterilization, and cooling phases. Accurately measuring this time is crucial for ensuring the effectiveness of the sterilization process, as it helps healthcare facilities maintain sterile environments and comply with regulatory standards. The completion of this cycle is essential for determining whether the instruments are safe for use, making it a critical metric in infection control protocols.
