CBSPD Technician Certification Exam Study Terms Bacillus stearothermophilus An organisms that a is commonly used as an indicator organism for the appropriate functioning of autoclaves because it grows at 56°C Bacillus atrophaeus spore used to monitor EtO and dry heat sterilization efficacy Bacteria (microbiology) single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission Bacteriocidal agent that kills bacteria Bacteriostatic inhibits growth of bacteria Bioburden The number of viable organisms in or on an object or surface or the organic material on a surface or object before decontamination or sterilization. Biological indicator A quality control mechanism used in the process of sterilization. It consists of a closed system containing harmless, spore-forming bacteria that can be rapidly cultured after the sterilization process. Biological Monitor Verifies sterilization by confirming that all spore-forming microorganisms have been destroyed biopsy the removal of living tissue from the body for diagnostic examination Bowie-Dick Test Test used to evaluate the efficacy of the air removal in a dynamic-air-removal steam sterilizer. Performed Daily. Bacillus Rod shaped bacteria Cavitation The ultrasonic cleaner removes debris from instruments by a process called cavitation. High-frequency sound waves are generated through a water bath. Cavitation causes tiny air spaces trapped within debris to implode (explode inwardly), and this releases the debris from the surface of the instrument. Chemical Indicator A chemical indicator (monitor) is a chemically treated strip that changes color when exposed to a specific temperature, pressure, and humidity. The pellet form of this indicator is contained in a glass vial. Chemical monitors are available for both steam and EO sterilization. The chemical responds to high temperature, pressure, and humidity but does not register exposure time, which is critical to the sterilization process. A chemical monitor should be placed inside and outside all packs to be sterilized. After the cycle, the indicator must be retrieved and interpreted. EtO Sterilization Process 1. Preconditioning 2. Preheat 3. Add moisture 4. Add EtO, allow to penetrate load and sterilize by alkylation Event-related sterility Sterility determined by how a package is handled rather than time elapsed; a package is considered sterile until opened or the integrity of packaging material is damaged Epidemiology Branch of medical science concerned with the incidence, distribution, and control of diseases that affect large numbers of people. fenstrated having openings Fomite A physical object that serves to transmit an infectious agent from person to person. gram positive Describing the group of bacteria that have a cell wall that is structurally less complex and contains more peptidoglycan than the cell wall of gram-negative bacteria. Gram-positive bacteria are usually less toxic than gram-negative bacteria. gram negative Describing the group of bacteria that have a cell wall that is structurally more complex and contains less peptidoglycan than the cell wall of gram-positive bacteria. Gram-negative bacteria are often more toxic than gram-positive bacteria. germicide a substance that destroys microorganisms Glutaraldehyde Solution used for high-level disinfection and sterilization Staphylococcus a genus of gram-positive bacteria that are potential pathogens, causing local lesions and serious opportunistic infections, a cluster of cocci
