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
Learn about the importance of sterilization in reusable medical devices, its ideal methods and requirements. Sterilization is a crucial process to eliminate all microorganisms, including spores.
