Ch. 8 Flashcards
What is clean?
The removal of all visible and non-visible soil and other foreign material from the medical device being reprocessed
Where does decontamination start?
Decontamination starts at the point of use.
What is a decontamination area?
The location within a healthcare facility designated for the collection, retention, and cleaning of soiled and/or contaminated items.
What is the goal of decontamination?
To remove all soil seen and unseen.
How many air exchanges should there be in the decontamination area.
The ventilation system should allow for no less than 10 air exchanges per hour.
What kind of pressure should it be in the decontamination area.
The area should be under negative pressure.
What is the temperature in the CSD?
60°F- 65°F
Why should the temperature be low in the CSD?
Low temperature keeps the technicians cool and inhibits the growth of microbes.
What is relative humidity?
the amount of water vapor in the atmosphere
What is the humidity level in the decontamination area?
30%-60%
Where should emergency eyewash be located?
Withing 10 seconds or 30 meters of areas of potential chemical exposure.
What is the first line of defense for reducing contaminates?
Maintaining a clean workspace.
Name the 4 cleaning procedures?
- Horizontal work surface cleaned and disinfected
- Spills spot clean immediately
- Floors disinfected and cleaned every day
- Biohazard waste should be removed frequently
What is biohazard waste?
Waste containing infectious agents that present a risk or potential risk to human health.
Name the PPEs.
Head covering Eye protection (goggles, face shield) Fluid-resistant face mask Strong general-purpose utility gloves Skid-resistant decon shoe covers Employer-provided cloth scrub attire
The workflow goes from ____ to____.
Dirty to clean
Name the 3 sinks in the 3 sink method.
Wash sink
Intermediate sink
Final rinse sink
Describe the wash sink.
Warm water 80°F-110°F
Add chemical according to IFU
Where you remove soil
Use a brush in a to and frow motion underwater
Why should you brush underwater?
To prevent aerosol ( water particles in the air).
Describe the second sink.
Initial rinse
Plain or softened water
Removes chemicals or residue
Describe the third sink
Final rinse
Distilled, Deionized, or Reverse Osmosis water
Rinse off cleaning chemicals and pyrogens
Water that has had all minerals removed.
Deionized water
Water that has been heated to steam then allowed to cool removed impurities
Distilled water
The process of water being purified after being forced through a semipermeable membrane.
Reverse Osmosis
What is the primary cleaner in the CSD?
Pure Water
What is turbidity?
Dirty water
Name some manual cleaning tools.
Brushes Cleaning Cloths Sponges Water irrigators Forced Instumentt Air
When is manual cleaning performed?
On delicate devices
When IFU calls for it
To clean lumens
Laparoscopic instruments
Name the Mechanical Cleaners
Ultrasonic Cleaner
Irrigation Sonic Cleaner
AER
Wash Cart
What method do ultrasonic cleaners use to clean?
Cavitation
Low-pressure bubbles implode and dislodge soil from the instrument
Cavitation
Why should you rinse items cleaned in the ultrasonic cleaner?
ultrasonic cleaner dislodges the soil and pushes it to the top. The residue can settle on the instruments so they must be rinsed.
What is an AER?
Automatic Endoscope Reprocessor
What are the 3 methods of cleaning?
Precleaning
Manual Cleaning
Mechanical cleaning
What is the advantage of mechanical equipment?
They save time and produce consistent processes.
3 Types of Detergents
Emulsifier
Surfactant
Chelating Agents
Name the 3 enzyme products.
Protease
Lipase
Amylase
What type of soil does protease eat?
Protein
What type of soil is lipase for?
Fat
What type of soil is amylase for?
Starch
Name the 4 Types of Chemicals
Enzyme products
Detergents
Descaler
Pre-soaking chemicals
Where are pre-soaking chemicals used?
At the point of use.
Lowers surface tension and increases the solubility
Surfactant
Bind substances such as oil and water together
Emulsifier
A substance that produces fever when introduced/ released into the blood.
Pyrogen
What are the 4 steps of cleanliness testing?
Swab
Prepare
Read
Record
Name the steps in the decontamination process.
Point of use cleaning
Soiled receiving
Cleaning
Inspection
Acuta postoperative inflammatory reaction in which a noninfectious substance enters the anterior segment and induces toxic damage to the intraocular tissues
