Sterilization第 48 / 100 题
An ozone sterilization system is being introduced. Which statement about ozone sterilization is accurate?
a.Ozone is generated from ethylene oxide and requires the same aeration as EO
b.Ozone sterilizes at 270 degrees F and can replace steam for textile packs
c.Ozone is used primarily for oils, powders, and anhydrous materials
d.Ozone is generated on demand from oxygen and water, sterilizes at low temperature, and reverts to oxygen with no toxic residue
解析
Ozone sterilizers create the sterilant on site from medical-grade oxygen and water, which removes the need for stored chemical cartridges, and the ozone converts back to oxygen at the end of the cycle. It is a low-temperature method for heat-sensitive and moisture-sensitive devices, not a steam substitute for textiles. Dry heat, not ozone, is the method for oils and powders, and ozone is unrelated to ethylene oxide.
