Point-of-use |
Occurs when a medical device is processed immediately before use, and/or close to the patient care area. |
|
Flash sterilization |
The process by which unwrapped instruments are sterilized for immediate use when an emergency situation arise. |
|
Flash sterilization can be accomplished with three types of Cycles what are they? |
Gravity Cycles Pre vacuum Cycles The express cycle |
|
Gravity Cycles |
Are traditionally called flash cycles and they may be pre-programmed into the control systems of steam sterilizers. |
|
Pre vacuum Cycles |
We're added to sterilizers used in operating rooms when more complex operating room instrumentation(ex ortho/neuro) were manufactured to permit gravity and pre vacuum sterilization |
|
The express cycle |
Is a limited application cycle for a single instrument wrapped in a single layer wrap. |
|
Porous |
Possessing or full of pores(minute openings) |
|
The ventilation system should provid at least how many air exchanges. |
10 air exchanges per hour |
|
Class 5(chemical integrators) |
Integrating indicators designed to react to all critical parametres over a specificed range of sterilization Cycles |
|
Conventional biological indicators(BIs) are |
Strips that have been populated with a standardized viable population of bacterial spores. |
|
The incubation temperature for geobacillus stearothermophilus is |
122-140°F (50-60°C) |
|
For routine monitoring AAMI recommends that a biological test be done at least |
Weekly preferable everyday that the sterilizer is used |
|
The residual air removal test is know as the |
Bowie-Dick Test |
|
Pounds per square inch gauge(psig) |
A measure of ambient air pressure the pressure that a gas would exert on the walls of a 1 cubic foot container |
|
The documentation for each flash cycle should include the: |
*Patient name *Contents of The Flash sterilization load *Type of sterilization cycle used *Cycle parameters *Reason for Flash sterilization *Signature of Staff person |
|
Critical devices |
Instruments are objects introduced directly into the bloodstream or other normal sterile areas of the body(ex:surgical inst,cardiac catheters,&needles) |
|
Semi-critical devices |
Those which come in contact with none intact skin or mucous membrane(ex:endoscopes, anesthesia breathing circuits) |
|
Non-critical devices |
Those that contact intact skin(ex:crutches,bed boards) |
|
Oxidation |
The process by which a molecule atom or ion loses an electron. The act or process of oxidizing, chemical breakdown of nutrients for energy |
|
Molecule |
The smallest quantity of matter that can exist in a free state and retain all of its properties |
|
Atom |
The fundamental unit of a chemical element |
|
Ion |
An electronically charged particle that is formed by the loss or gain of one or more electrons |
|
Electron |
A negatively charged particle that moves around the nucleus(central core) of an atom |
|
Oxidizing agent |
A material that removes electrons from another substance |
|
Oxidative chemistries |
A class of compounds that contain an addition atom of oxygen bound to oxygen and that uses oxidation to interrupt cell function |
|
Macromolecules |
Large molecules(proteins, carbohydrates, lipids, and nucleic acids) within a microorganism |
|
Peracetic acid(PA) |
A liquid oxidizing agent that effectively kills bacteria at low temperatures. |
|
PA has been used in a liquid chemical sterile processing system since when |
1988 |
|
Sterilization documentation is not required for items that are flash sterilized (true or false) |
False |
|
Instruments must be clean before flash sterilization (true or false) |
True |
|
Flash sterilization is rarely performed in hospitals (true or false) |
False it's perform in every hospital of the country |
|
Peracetic acid is a liquid oxidizing agent that effectively kills bacteria at low temperatures (true or false) |
True |
|
Currently there are no process monitors available for peracetic acid sterilization processes (true or false) |
False: A microprocessor that continually detects & monitors various process parameters through ever cycle. |
|
A diagnostic cycle on the peracetic acid system should be run everyday (true or false) |
True |
|
Hydrogen peroxide is an example of an oxidative chemistry (true or false) |
True |
|
Liquid peracetic acid is difficult to rinse from items |
False |
|
Ethylene oxide is not used for a point-of-use processing because of its long cycle items (true or false) |
True |
|
High-level disinfection is appropriate for a semi-critical devices (true or false) |
True |
