Low-Temp Methods
The sterilization method used for items that cannot withstand high temperatures.
What is low-temperature sterilization?
The process by which EtO kills microorganisms.
What is alkylation?
The process by which hydrogen peroxide gas plasma kills microorganisms.
What is oxidation?
The process by which ozone kills microorganisms.
What is oxidation?
This is a general term for the probability of a viable microorganism being present on an item after sterilization
What is Sterility Assurance Level (SAL)?
This gas is used in EtO sterilization.
What is ethylene oxide?
The process that removes EtO residuals from sterilized items.
What is aeration?
The common name for hydrogen peroxide gas plasma sterilization
What is gas plasma?
The byproduct of ozone sterilization
What is oxygen?
This is a low-temperature sterilization method that uses oxidation.
What are hydrogen peroxide gas plasma and ozone?
This is a common byproduct of hydrogen peroxide gas plasma sterilization
What are water and oxygen?
The biological indicator used to monitor EtO sterilization
What is Bacillus atrophaeus?
The material that is incompatible with hydrogen peroxide gas plasma.
What is cellulose (or liquids)?
A safety concern associated with ozone sterilization
What is that it is a toxic gas?
This method has the longest cycle time.
What is ethylene oxide (EtO)?
This gas is used in ozone sterilization.
What is ozone?
A disadvantage of EtO sterilization
What is long cycle time, toxic residue, the need for aeration (any of these)?
The advantages of Hydrogen Peroxide Gas Plasma Sterilization
What is fast cycle time, and that its by-products are water and oxygen (relatively safe)
The typical cycle time for ozone sterilization
What is 4.5 hours?
This method has the widest material compatibility.
What is ethylene oxide (EtO)?
A key factor in choosing a low-temperature sterilization method.
What is material compatibility?
The OSHA-required limit for EtO exposure.
What is Permissible Exposure Limit (PEL)?
What are the byproducts of hydrogen peroxide gas plasma?
