Decontamination Cycle Mechanics

The conditioning phase establishes optimal environmental parameters by reducing chamber humidity to 30-40% relative humidity and stabilizing temperature at 20-25°C. This preparation ensures maximum hydrogen peroxide vapor penetration and prevents condensation formation that could compromise sterilization efficacy.

During the decontamination phase, hydrogen peroxide vapor is introduced at concentrations between 140-1400 ppm, depending on load characteristics and cycle requirements. The vapor distribution system ensures uniform concentration throughout the chamber while automated monitoring prevents hot spots or dead zones where sterilization might be incomplete.

Vapor Penetration and Contact Time

Industry research conducted by contamination control specialists demonstrates that proper vapor penetration requires specific contact times based on material density and packaging configuration. Porous materials typically require 15-20 minutes of exposure, while dense items may need extended contact periods to achieve complete sterilization.

The aeration phase removes residual hydrogen peroxide vapor through controlled air exchanges, reducing concentrations to safe levels (typically <1 ppm) before chamber access is permitted. This process utilizes catalytic conversion systems that break down hydrogen peroxide into water vapor and oxygen, ensuring no harmful residues remain on transferred materials.

Temperature and Humidity Control

Critical to VHP effectiveness is maintaining precise environmental conditions throughout the sterilization cycle. Temperature fluctuations beyond ±2°C can significantly impact vapor behavior and sterilization kinetics. Similarly, humidity levels must be controlled within narrow parameters to prevent condensation while ensuring adequate vapor dispersion.
