Dear Irmelinda.

Unfortunately I can’t find standard that can say that all loads in hydrogen peroxide sterilizers must to be controlled by biological indicators. Usually we can use this type of sterilization only for MD only with manufactory demands (ISO 17664). In last 5-6 years I was so a lot of examples that European manufacturers started to produce MD from that technologies and materials that can give us a chance to sterilize it by steam.
In Guideline of CDC for disinfection and sterilization in healthcare facilities (2008) you can find that “Microbicidal Activity. This process has the ability to inactivate a broad range of microorganisms, including resistant bacterial spores. Studies have been conducted against vegetative bacteria (including mycobacteria), yeasts, fungi, viruses, and bacterial spores. Like all sterilization processes, the effectiveness can be altered by lumen length, lumen diameter, inorganic salts, and organic materials” In that case if you like sterilize MD with long lumen with special PCD with lumens. Unfortunately I was not seeing this type PCD for gas plasma (because there is no exist demands in ISO 11140).

IMHO: You can’t validate gas plasma sterilizers because there is no technical standards about validation of gas plasma sterilization. There is no exist 4 class of CI (ISO 11140) for gas-plasma sterilization. You are really needed to use this type of sterilization?

Hope it’s help.
