What should be the condition of lumens when using hydrogen peroxide as a sterilizing agent?

When using hydrogen peroxide as a sterilizing agent, the condition of lumens should be dry to ensure effective sterilization. Hydrogen peroxide is a potent oxidizing agent that requires the presence of sufficient vapor or gas to achieve its sterilization effects. Moisture can impede the penetration of the hydrogen peroxide vapor, making it less effective at reaching all surfaces within the lumen and thereby compromising the sterilization process.

In a dry lumen, hydrogen peroxide can thoroughly circulate and adequately interact with microbes present on the surfaces, ensuring a higher level of sterilization. The use of hydrogen peroxide in dry conditions maximizes its efficacy in breaking down microorganisms without the interference of moisture that could lead to incomplete sterilization or degradation of the material being sterilized.
