Sterilization • Sterilization is the process where all the living microorganisms, including bacterial spores are killed. • Sterilization can be achieved by physical, chemical and physiochemical method Chemical indicators Tape with lines that change color when the intended temperature has been reached. Pellets in glass tubes that melt, indicating that the intended temperature and time have been reached. Indicator strips that show that the intended combination of temperature, time, and pressure has been achieved PowerPoint presentation compilation on sterilization & disinfection. Chemical indicator - internal indicator indicates that process parameters have been met in the interior of the wrapped or packaged set Chemical indicators (CI) are used to assess if the required time and temperature were attained during the sterilisation process. One.
Using bacterial spores to monitor the sterilization process is referred to as biologic monitoring (or spore-testing), and the bacterial spores used for monitoring the sterilization process are referred to as biologic indicators (BIs). The sterilization process also can be monitored by using chemical indicators (CIs) that change color or form. Changing appearances in color or pattern, the sterilization indicators visually show if cleaning conditions are passing or procedures have been completed. Eliminating any confusion or possibility instruments will not be sterile, indicators are used routinely in clinical and research environments where contamination elimination is crucial Biological Indicators & Chemical Indicators OSAP 2010 Annual Symposium 1 Biological Indicators and Chemical Indicators BIs play an important role in the monitoring of sterilizers, along with physical and chemical indicators Biological Indicators.
