Study Notes
Sterilization Definition and Requirements
- Sterilization is the complete destruction of microorganisms, including bacterial spores.
- This level of decontamination is required for all reusable invasive medical devices (RMD).
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
- Uses 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
