enzymatic detergent
Cleaning agents containing enzymes that break down specific organic soils on medical instruments.
ethylene oxide sterilization
Low-temperature sterilization method using ethylene oxide gas for heat-sensitive medical devices.
event-related sterility maintenance
Sterility maintenance concept based on package integrity rather than arbitrary time limits.

fractional sterilization
Multi-cycle sterilization method using repeated heating and cooling periods separated by incubation.
Geobacillus stearothermophilus
A heat-resistant bacterial spore used as the standard biological indicator organism for steam sterilization validation.
gravity air removal
A sterilization process that relies on steam's natural buoyancy to displace air from the sterilization chamber.
gravity displacement sterilizer
A steam sterilizer that relies on gravity to remove air from the chamber, displacing it with steam from the bottom up.
high-level disinfection
Chemical or thermal process that destroys vegetative bacteria, viruses, fungi, and some bacterial spores.
hydrogen peroxide sterilization
Low-temperature sterilization method using vaporized hydrogen peroxide plasma technology.
immediate use steam sterilization
Steam sterilization of unwrapped instruments for immediate use when standard sterilization is impractical.
instrument functional testing
Systematic evaluation of surgical instruments to verify proper mechanical operation and safety before sterilization and...
instrument functional verification
Post-processing inspection to confirm that surgical instruments operate correctly and meet performance specifications.
