Which monitoring method involves checking readings on indicators?

The correct response highlights that physical monitoring involves checking readings on indicators. In the context of infection control, particularly in sterilization processes, physical monitoring entails observing gauges, thermometers, and other indicators that provide real-time data reflecting the conditions within sterilizers. For instance, monitoring temperature and pressure during a sterilization cycle ensures that these parameters reach the necessary levels for effective sterilization.

This contrasts with other monitoring methods. Chemical monitoring uses colored indicators that change in response to temperature or chemical exposure during sterilization, but it does not involve regular readings; rather, the changes are observed post-process. Quality assurance is a broader concept that encompasses various protocols and assessments to ensure safety and efficacy in dental practices, rather than focusing specifically on indicator readings. Biological monitoring, which employs live spores to confirm sterilization effectiveness, does not involve direct reading of indicators but rather requires culturing and observation to establish the sterility of the process.
