1

BACTERICIDAL

Able to kill bacteria

2

BACTERIOSTATIC

Chemical agent capable of inhibiting the growth of bacteria

3

BIOBURDEN

The number of contaminating microbes on an object

4

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

5

BOWIE-DICK TEST

A test that identifies air leaks and ineffective air removal in the steam sterilization process

6

CAVITATION

A process in which air bubbles are imploded (burst inward), releasing particles of soil or tissue debris

7

CHEMICAL STERILIZATION

A process that uses chemical agents to achieve sterilization

8

CLEANING

A process that removes organic or inorganic soil or debris by using friction, detergent, and water

9

DISINFECTION

Destruction of microorganisms by heat or chemical means

Does not produce sterility, as not all microbial forms are destroyed in the process

10

EXPOSURE TIME

This is the amount of time goods are held in specific conditions during disinfection or the sterilization process

Exposure time varies with the size of the load, type of materials being sterilized, and type of agent used

Also called the hold time

11

HIGH-LEVEL DISINFECTANT (HLD)

A process that reduces the bioburden to an absolute minimum

12

IMMEDIATE USE STEAM STERILIZATION (IUSS)

Rapid sterilization of instruments to be used immediately

Process was previously called flash sterilization

13

PERACETIC ACID

A chemical used in the sterilization of critical items

14

PRION

Infectious protein particle that is a unique pathogenic substance containing no nucleic acid

Resistant to most forms of disinfection and sterilization normally used in the health care setting

15

SPORICIDAL

Able to kill spores

16

TERMINAL CLEANING

A daily process in which exposed surfaces of the OR are cleaned and disinfected

17

TURNOVER

Cleaning, disinfection, and preparation of the OR between patients

18

WASHER-STERILIZER/DISINFECTOR

Equipment that washes and decontaminates instruments so they can be safely handled by personnel

19

CLEAN

The absence of visible soil on a surface
