    Study Notes

    Sterilization Overview

    • Complete destruction of microorganisms, including bacterial spores.
    • Essential for all Reusable Medical Devices (RMD) to prevent infection.

    Ideal Sterilization Methods

    • Rapid throughput to ensure efficiency.
    • Easily validated to maintain high standards of safety and effectiveness.
    • Capable of processing wrapped items, allowing safe storage post-processing without contamination risks.

    Common Sterilization Methods

    • Steam Sterilization (Moist Heat)

      • Operates under high pressure.
      • Cycle time approximately 40–60 minutes.
    • Dry Heat Sterilization

      • Functions similarly to an oven, using normal atmospheric pressure.
      • Cycle time can extend up to 2 hours.
    • Gas Plasma Sterilization

      • Utilizes ambient temperature for effective sterilization.
      • Cycle time ranges from 45 to 75 minutes.
    • Ethylene Oxide (EO) Sterilization

      • Can occur at sub-atmospheric or high pressure.
    • Low Temperature Steam and Formaldehyde Vapor

      • A method that ensures safe processing of sensitive items.
