Final answer:
LTGP sterilization uses low temperature, low humidity, and high pressure to sterilize using chemicals in a plasma state, which allows thorough sterilization of heat-sensitive instruments without damaging them.
Step-by-step explanation:
The parameters for Low Temperature Gas Plasma (LTGP) sterilization are low temperature, low humidity, and high pressure. LTGP sterilization uses plasma, an ionized gas, and substances such as hydrogen peroxide or peracetic acid in a plasma state to achieve sterilization. This method is effective as it penetrates surfaces and kills microorganisms, including endospores. The low temperature is beneficial in that it prevents damage to heat-sensitive instruments, while the plasma state of the chemicals ensures thorough sterilization without leaving toxic residues, since they break down into innocuous compounds.
