    Study Notes

    Sterilization Definition

    • Complete destruction of microorganisms including bacterial spores

    Ideal Sterilization Methods

    • Have rapid throughput
    • Are easily validated
    • Are capable of processing wrapped items to enable storage after processing without the risk of environmental contamination of processed items

    Sterilization Methods

    • Steam (moist heat) at high pressure: • Cycle time: approximately 40-60 minutes
    • Dry Heat: • Similar to an oven • Using normal pressure • Cycle time: up to 2 hours
    • Gas Plasma: • At ambient temperature • Cycle time: 45-75 minutes
    • Ethylene Oxide (EO): • At sub-atmospheric or high pressure
    • Low Temperature Steam and Formaldehyde Vapor: • Cycle time: not specified
