Study Notes

Sterilization and Disinfection

The primary purpose of cleaning in the context of sterilization and disinfection is to remove dirt, debris, and microorganisms from surfaces and equipment.

Sterilization

Sterilization is the process of completely eliminating all forms of microbial life, including spores, from a surface, equipment, or medium.
The purpose of sterilization is to create a completely sterile environment, free of all microorganisms.

Sterilization vs Disinfection

The main difference between sterilization and disinfection is the level of microbial killing: sterilization eliminates all microorganisms, while disinfection reduces the number of microorganisms to a safe level.

Monitoring in Sterilization

The purpose of monitoring in the context of sterilization is to ensure that the sterilization process is effective and consistent, and that the desired level of sterility is achieved.

Antiseptics in Disinfection

The primary purpose of antiseptics in the context of disinfection is to reduce the number of microorganisms on skin or mucous membranes, preventing infection and promoting wound healing.
