When using the warm cycle of the EtO sterilizer, what is the minimum sterilization temperature in Fahrenheit?

The minimum sterilization temperature in Fahrenheit for the warm cycle of the ethylene oxide (EtO) sterilizer is indeed 85 degrees. EtO sterilization is a widely used method for sterilizing medical equipment, particularly those that are heat and moisture sensitive.

The warm cycle of the EtO process is designed to effectively kill a wide range of microorganisms while ensuring that the integrity of sensitive instruments remains intact. The temperature must be maintained at a minimum of 85 degrees Fahrenheit to ensure that the ethylene oxide gas can penetrate the materials and achieve the desired microbial kill rates. This temperature allows the gas and moisture to interact effectively, enhancing the sterilization process and ensuring that the equipment is safe for subsequent use.

Sterilization below this temperature could lead to insufficient penetration and effectiveness of the sterilizing agent, compromising the sterility assurance levels necessary for patient safety.
