4 - Judgement day: the machines have taken over Flashcards
1
Q
What is the load carrier?
A
Where the instruments are placed in the WD
2
Q
What are the stages in an AWD?
A
- flush/prewash
- main wash
- rinse
- thermal disinfection
- drying
3
Q
Describe the flush stage of an AWD.
A
- saturates contamination and removes gross contamination
- this is when prions and proteins are removed
- less than 35 degrees
4
Q
Describe the main wash stage of an AWD.
A
- supplemented by detergent to effectively remove biological matter
- this is when prions and proteins are removed
- temperature dependent on chemical MI
5
Q
Describe the rinse stage of an AWD.
A
- removes remaining residue, both biological and chemical, before disinfection
- less than 65 degrees
6
Q
Describe the thermal disinfection stage of an AWD.
A
- actively kills micro-organisms with heated water
- 90-95 degrees for at least one minute
7
Q
Describe the drying stage of an AWD.
A
- hot air is used to remove moisture from the surface of the instruments
- typically 100 degrees
8
Q
Why must washing occur prior to disinfection?
A
- prions and some proteins cannot be deactivated by heat
- heat would instead adhere these proteins to the surface of the instrument
9
Q
What are the daily tests for an AWD?
A
- spray arms spin freely
- spray jets are not blocked
- no debris in the filter or parts of instruments or potential blockages
- check door seal and wipe clean
- check chemical levels
- record temperature of first cycle (automatic control test, ACT)
10
Q
What are the loading requirements of an AWD?
A
- use the load carrier
- clip trays positioned correctly
- no overlapping equipment
- hinged instruments must be opened at the hinge
- any instruments with multiple parts should be disassembled
11
Q
How is inspection carried out?
A
- after using the AWD all instruments should be inspected
- illuminated magnifier used to check for damage or remaining contamination
12
Q
What happens if an instrument does not pass inspection due to contamination?
A
Either placed in ultrasonic bath or manually cleaned
