IAHCSMM Chapter 16
The "newest" low temperature sterilization process.
This method of low temperature sterilization has been in use since the 1960s.
Less than 1 hour
Cycle time for items sterilized using hydrogen peroxide gas plasma.
Bacterial spore used to test ethylene oxide sterilization cycles.
Cycle time for items sterilized using ozone sterilization.
140F aeration time recommended for items sterilized with ethylene oxide.
Bacterial spore used to test hydrogen peroxide gas sterilization cycles.
Cycle time for items sterilized using ethylene oxide sterilization.
Sets exposure standards for chemical sterilants.
Requires that sterilants be rigorously tested before being marketed.
Of the 3 major low temperature sterilants, ethylene oxide has the longest instrument turnaround time.
Ethylene oxide kills microorganisms by a process called oxidation.
Ethylene oxide, hydrogen peroxide gas plasma, and ozone sterilization process must all be monitored using chemical, physical, and biological monitors.
Ethylene oxide, hydrogen peroxide gas plasma, and ozone sterilization can all use the same packaging materials.
Ethylene oxide has better penetration capabilities then ozone and hydrogen peroxide gas plasma.
Ethylene oxide is a toxic gas.
Cellulose-containing packaging materials are not compatible with hydrogen peroxide gas plasma sterilization.
Information about a device's compatibility with a specific sterilization process should be obtained from the device's manufacturer.
Aeration is required for items sterilized in ozone sterilization processes.
Relative humidity is a required cycle parameter for ozone and ethylene oxide sterilization.
