Ethylene oxide is used as a sterilizing agent, disinfecting agent and fumigant as a mixture with carbon dioxide (8.5–80% of ethylene oxide), nitrogen, or dichlorodifluoromethane (12% ethylene oxide). It is applied for gas-phase sterilization of medical equipment and instruments, packaging materials, clothing, and surgical and scientific ...
Ethylene oxide treatment is the most common chemical sterilization method, used for approximately 70% of total sterilizations, and for over 50% of all disposable medical devices. [ 26 ] [ 27 ] Ethylene oxide treatment is generally carried out between 30 and 60 °C (86 and 140 °F) with relative humidity above 30% and a gas concentration between ...
Sterilant gas monitoring is the detection of hazardous gases used by health care and other facilities to sterilize medical supplies that cannot be sterilized by heat or steam methods. [1] The current FDA approved sterilant gases are ethylene oxide, [2] hydrogen peroxide [3] and ozone. [4]

Sterilization can also be achieved using ethylene oxide (ETO) gas. This process was created in the 1950s by the US military [4] and is used on items that cannot withstand the high temperatures of steam sterilization. ETO sterilization takes far longer than steam sterilization and is hazardous to workers, so alternative methods were created in ...
Plaintiffs sued Sterigenics and Sotera Health LLC over its use of ethylene oxide, a chemical said to cause cancer, according to the U.S. Environmental Protection Agency. The plant, located near ...
The "gas diffusion" [1] method of using ethylene oxide was particularly useful to Andersen whose invention of the first double lumen nasogastric tube was being used by his colleagues at Bellevue Hospital in New York, NY, where he was chief resident. At that time a single lumen Levin tube was employed clean and packaged, but not sterile.
