Anteroom
an ISO Class 8 room or area immediately before the buffer room in which hand washing, hygiene, and garbing are done and supplies and ingredients are gathered between the pharmacy department and the cleanroom or buffer area.
Asepsis
the absence of pathogenic microorganisms
Aseptic hand washing
- a more aggressive soap and water hand washing procedure, followed by use of an antiseptic agent before donning sterile attire
Aseptic technique
- the manipulation of sterile products and devices to avoid contamination by disease-causing organisms; includes cleanroom protocols and hand-washing and gowning procedures
Autoclave
- a device that generates hear and pressure to sterilize objects instruments, and measures vessels
Auxiliary Clamp
- slide clamp used to completely stop the IV solution from flowing
Bacteria
- a small, single-celled microorganism that can exist in three main forms, depending on type: spherical (i.e., cocci), rod-shaped (i.e., bacilli), and spiral (ie., spirochetes)
Buffer room
- an ISO Class 7 or cleaner area where the PEC s are physically located; also called the IV or cleanroom
Clean room
- an ISO-classified room (or two-room configuration of a cleanroom area) in which the concentration of airborne particles is controlled to meet a specified air-borne-particulate cleanliness class to prevent particle and microbial contamination of CSPs; also called the IV room or buffer room
Compounded Sterile Preparation
- medication prepared with aseptic technique in a sterile, cleanroom facility
Critical Site
- the part of the syringe and/or needle that is at risk for contamination by couch or airflow interruption
Disinfectant
- a chemical agent such as sterile 70% IPA used on inanimate surfaces and objects to destroy fungi, viruses, and bacte-ria, but not necessarily their spores
Distillation
- process of boiling a liquid and capturing the condensed gases or vapor back into a purified liquid form
Drip chamber
- the small, open space just below the spike adaptor where the drops of fluid from the IV bag into the tubing are counted by the nurse to determine the flow rate of the IV solution
Drop factor
- factor the number of drops that an IV cubing delivers to provide 1 mL.; this number may be used by nurses to calculate the IV flow rate when using certain types of primary IV cubing; also called drop set or drip set
Epidemic
- a regional widespread contagious disease
Filtration
- funneling of a liquid or gas through filters, or mesh screens with minute holes too small for biological and chemical contaminants to pass through
high-efficiency particulate airflow (HEPA)
- filter a device used to filter over 99% of particulate matter from the air to establish an asepric environment in which to prepare CSPs
Horizontal Laminar Air Flow Workbench
- also known as a laminar hood, a PEC (with an ISO Class 5 air quality in its DCA)used to prepare IV drug admixtures, nutrition solutions, and other parenteral products aseptically
Injection Port
- a connector on the IV cubing which allows the injection of IV fluid or medication other than that in the current IV bag to be infused into the patient's vein
In-Line Filter
- ISO IV administration set - a device used in the IV line to remove contaminants such as glass, fibers, bits of rubber, and bacteria from IV fluids
IVPB
- a small-volume paren-teral (SVP) infusion (50 mL, 100 mL., 250 mL) containing medications attached to a primary LVP IV solution
LVP (Large Volume Parenteral)
- IV solutions of more than 250 mL that may contain medications, nutrients, or electrolytes
Positive Pressure
- air is being blown into a room and therefore it has higher pressure than the adjacent spaces so the net airflow is out of the area
