Because spores used in BIs are more resistant and present in greater numbers than are the common microbial contaminants found on patient care equipment, an inactivated BI indicates that other potential pathogens in the load have also been killed.” “Because chemical indicators do not prove sterilization has been achieved, a biological indicator (i.e., spore test) is required.” CDC: Centers for Disease Control and Prevention Sterilization Monitoring – Infection Control in Dental Settings BI是灭菌监测最首选方法，因为它直接用最 难芽孢来测定只有BI能证实灭菌过程达到 ? 3M 2014 All rights reserved * AORN As a direct measure of lethality, the BI has become the “Gold Standard” for use in identifying sterilization Process failures. Even marginal failures caused by the inability to reach temperature, inadequate air removal, or superheated steam can be detected by BIs. For these reasons, and more, many facilities are choosing to follow standards closely and in some cases taking standard practice to the next level when it comes to monitoring with BIs.
