Don't Procrastinate Flashcards
what must the transport container be
rigid sided
tight fitting lid
leak proof
colour coded or clearly marked
what must the washer disinfector be
validated to establish cycle parameters
loading patterns followed
daily and weekly testing
what should a lit magnifier be used to
identify damage present on instrumentation
identify any spots of residual contamination
what is the ultrasonic used for
remove hard to reach contamination
as a secondary or backup method
must be degassed and tested before use
what must a steriliser be
tested on a daily and weekly basis
used with purified water
have an annual insurance test
in what ways is a time a major factor in all stages of decontamination
how long since instruments were used
how long does wash phase need to be
how long is WD cycle
what are the critical time/temperature settings for thermal disinfection
how long will packaging and sterilisation process take
how long does processing cycle take overall
what are the major factors in decontamination process
time
temperature
water
chemicals
energy
what does the sinner circle show
r elements that are required for successful cleaning process
(energy, temperature, chemicals, time)
what happens if you increase or decrease any of the factors in the sinner circle
impact efficacy of the process
what kind of particulate does water pick up in the pipework
minerals
silicates
organics
metals
what is the measure of particulate in water called
conductivity
what is conductivity also referred to
total dissolved solids
what is the unit of measurement of conductivity
micro siemens
what are the kinds of purified water
distilled
de-ionised
reverse osmosis
sterile
how is distilled water produced
boiling and recondensing standard tap water
how is de-ionised water produced
passing water through an ion exchange that picks up things such as sodium, calcium and potassium
how is reverse osmosis water produced
semi permeable filter is used to remove particulate and bacteria from the water
how is sterile water produced
filtered and then sterilised
what is the conductivity level of pure water
4.3 micro siemens
what kind of detergent is used for enclosed process
high and low alkaline detergent
what kind of detergent breaks proteins down into smaller particles
enzymatic detergent
what kind of detergent is less harmful to operators skin
pH neutral detergent
what are the two ends of the detergent molecule
hydrophilic and hydrophobic
what end of the molecule is where contamination is drawn to
hydrophobic end
