Ethylene Oxide Sterilization is a method used to eliminate bacteria, viruses, and other pathogens from medical equipment and supplies. This process involves exposing items to ethylene oxide, a colorless gas that penetrates materials and disrupts the DNA of microorganisms, rendering them inactive. It is particularly useful for sterilizing heat-sensitive items that cannot withstand high temperatures. The sterilization process typically takes several hours and includes phases such as pre-conditioning, exposure, and aeration. After exposure, the items are aerated to remove any residual ethylene oxide, ensuring they are safe for use. This method is widely used in hospitals and laboratories for its effectiveness and versatility.
