VHPsterilointi

VHPsterilointi, also known as Vaporized Hydrogen Peroxide sterilization, is a low-temperature sterilization process used for heat-sensitive medical devices and equipment. It utilizes hydrogen peroxide vapor to kill microorganisms, including bacteria, viruses, and spores. The process typically involves a preconditioning phase to adjust humidity, followed by the introduction of vaporized hydrogen peroxide into the sterilization chamber. The vapor then penetrates packaging and sterilizes the device surfaces. After the sterilization cycle, the chamber is purged to remove any residual hydrogen peroxide, ensuring the safety of the equipment for subsequent use.

The advantages of VHPsterilointi include its ability to sterilize at low temperatures, making it suitable for delicate instruments that cannot withstand high heat or steam sterilization. It is also a relatively fast process compared to some other low-temperature methods. The byproducts of the process are primarily water and oxygen, which are considered environmentally friendly. VHPsterilointi is commonly employed in healthcare settings for sterilizing endoscopes, surgical instruments, and other medical equipment that requires a high level of sterility. Careful validation and monitoring are crucial to ensure the effectiveness of the sterilization cycle and the complete removal of hydrogen peroxide residues.
