Decon Flashcards
You see two nurses getting off bus in uniform. What would you bring up with them?
Appropriate infection control
professionalism
maintaining pts confidence
reputation of practice and profession
What would you include in a learning session on PPE?
ppe needs to be worn - during procedures - during cleaning - during decontamination - eyes, hands, clothes needs to be changed between pts correct disposal after usage and soiling patient ppe - eyes, clothes
how can you check staff are adhering to ppe regulations?
clinical audit
regular inspections by supervisor
4 reasons why you should manually clean before disinfection and sterilisation
- removal of gross debris - as could inhibit sterilisation process
- removal of restorative materials, e.g prophy paste and gic - as makes more difficult to clean on subsequent occasions or can affect function
- could contaminate biospy devices- causing mis-diagnosis
- required by law under Medical Devices Directive
Name and describe the classification of the types of instruments?
A critical instrument will be in contact with the blood stream. Therefore it must be sterile.
A semi-critical instrument are in contact with intact mucous membranes. Therefore sterile is preferable, or a
high level disinfectant.
A non-critical instrument are in contact with intact skin. These should be disinfected or cleaned
how does classification of instuments affect steriliser use?
A critical device must be sterile at the point of use. This requires sterile packaging, therefore a B or S type
steam steriliser.
4 main critical control points in life of instrument?
- Acquisition of the reusable device
- Cleaning
- Inspection
- Sterilisation
what characterises a LDU
- Sterilises singly wrapped or unwrapped items
- Processed items are not transported out the building or off-site
- Under the control of one or more clinicians who use the reprocessed devices
- Does not supply a third party
4 main elements of cleaning
- Chemicals - detergent
- Temperature - should not exceed 55 degrees- as coagulates proteins
- Energy - brushing, ultrasonic energy or water jets
- Time - as much needed to clean protein strip
What kind of water should be used for cleaning? why?
RO - reverse osmosis
Reverse osmosis as is demineralised so will not leave residue on instruments, the only water that can provide enough volume in a short time
What can you use to dry instruments?
dry non-linting disposable wipes/cloths
ppe used for decontamination
waterproof apron
face mask
rubber gloves
visor/ goggles
what should be near a manual cleaning station
first aid kit
eye wash bottle
washer disinfector cycle?
- Pre-wash (Flushing) - cold water, remove gross debris
- Wash
- Rinse
- Disinfecting
- Drying
classification of sterile?
there must be less than 1 in a million remaining viable micoorganisms
what can sterilisers not kill?
prions
standard time and temp for sterilisation?
134-137o
for a minimum of three
minutes holding time
result of not fully cleaning device before sterilisation?
It prevents steam coming into contact with the load
• The deposits may become fixed and difficult to remove
• It might contaminate the water in the steriliser encouraging bacterial growth
• Could cause adverse reactions in patients
what steriliser type(s) can produce sterile instruments?
B and S
- as can process wrapped instruments
Instruments processed unwrapped by N are just known as sterilised. not sterile, as cannot maintain sterility.
How do the steriliser types differ?
N - normal - passive air removal only. .:. cannot be used for anything wrapped or anything hollow
B - better - active air removal with vacuum. can take hollow, porous (dressings) and wrapped.
S - special - active forced air removal w/ vacuum. daily steam penetration test, periodic testing and maintenance required.
how to test sterilisers are working properly?
Parametric Release process.

What is meant by Standards?
produced by?
A document established by a consensus and approved by a recognised body, that provides, for common and
repeated use, rules, guidelines or characteristics for activities and their results, aimed at the achievement of
the optimum degree of order in a given context.
These standards may be either:
• British Standard
• European Norm
• International Standards Organisation
BS EN ISO
standards in processing:
• Validation
• Quality system
• Controlled environment
