Chapter 8 outline breakdown
How many CI or chemical indicators should there be in a wrapped set of instruments
At least 2
Class 1
Autoclave tape
What type of spore is in dry heat
Bacillus
What type of spore is used in the BI for EO
Bacillus
When should a BI PCD test be performed diring a qualification testing of steam sterilization
Before the bowie dick test
Placement of BI in LTGP
Bottom shelf in the back perferablr in top if tray
Class 2
Bowie dick test pack
Didfernce between a CI and a BI
CI monitors the sterilization process BI contains active spores
Placement of BI and PCD in EO
Center of load
Placement of BI in LTHP
Center of the top shelf
What class of chemical indicator parallels to the use of a BI thus is used when sterilizing loads with implants
Class 5 integrating indicators
Parameters for ozone
Concentration temp time
Paramters for EO
Concentration time humidity temp pressure
How are microorganisims killed for steam
Condensation
What is a spore
Dehydrated gram-positive rods sell with a thick hard shell like covering capable of surviving extreme heat lack of water and exposure to toxic chemicals and radiation
Class 6
Emulating indicators
How to load Rigid sterilization containers
Flat on rack with 1inch space (2.5 cm)
What type of spore is used in LTGP
GEOBACILLUS
What type of spore is in ozone
Geobacillus
What type of spore is used in LTHP
Geobacillus
Class 3
Glass ampule
Function of the drain line
Heat sensing thermometer, coldest part of sterilizer which is the greatest area of challenfe for a sterilizer. Where the bowie dick and BI is placed for testing
Class 5
Integrating indicator
Define master product
Most difficult to sterilize tray from a family of products
Class 4
Multi variable indicator
How to load paper platoc pouches
On their edge side
How to load textiles
On thier side
What part of the steam sterilizer presents the greatest challange for sterilization
Over the drain. This is the best location to ensure an effective test
How are microorganisims killed for LTGP LTHP OZONE DRY HEAT
Oxidation
Placement of BI in ozone
Placed anywhere in the load
Function of the sterilizer/ insulated jacket
Provides heat inside the chamber to prevent condensation from forming on chamber walls help to separate water droplets from the steam before the steam is injected into the chamber
Bi test and color change for LTGP
Purple = negative Yellow=positive
Bi test and color change for LTHP
Purple =negative Yellow=positive
Bi test and color change for steam
Purple= negative Yellow= positive
Bi test and color change for EO
Purple= negative Yellow= positive
What is the first course of action is a bowie dick test fails for the first time
Re run the test and document
Defined superheating
Steam pressure is too low for set temptature When he is added to dry steam in the absence of water
What is gravity displacement sterilization
Steam using passive air displacement
What is dynamic air removal sterilization
Steam using pre vac sterilizers by condensation
What does sal stand for
Sterility assurance level
What does an incomplete color change of a class 2 indicator mean
Sterilizer does not have proper air removal theevacuation is not functioning properly l. The test must be reran
What part of the steam sterilizer surronds the internal chamber
Sterilizer jacket
Describe the BI PCD USED FOR OZONE STERILIZATION
Syringe in a pouch
Pacement of BI in dry heat
The fullest and densest load
Why is the presence of humidity critical to EO sterilization
The penetration of bacterial cells and successful sterilization
What is the meaning of a positive biological indicator
The sterilization process may not have been effective
How to load basin sets
Tilted on their side
How to load Solid trays
Tilted on thier sides
Parameters for dry heat
Time temp
Parameters for LTGP
Time temp hydrogen peroxide
Parameters for steam
Time temp pressure
Ehat is the purpose of a control BI
To cerify thay the spore is viable
The use of a bowie dick test
To test the air removal
Dwhat is the purpose for biologically testing rigid containers
To verify the sterilizer is able to sterilize the inside container
What is an ideal result for a bowoe dick test
Uniform color means proper air removal
Function of the inside/internal chamber of a sterilizer
Where the sterilization takes place where the steam is injected from the sterilizer jacket
What is the incubation temp of a BI for steam sterilization
131-140 degrees
What is the target temp anf time and pressure for dynamic air removal
270 @ 4 min 28-30 psi 275 @ 3 min 28-30 psi
Sterilizer setting for bowie dick test
3-3 1/2 minutes @270 no drying
How long should packs be allowed to cool
30-120 min
Parameters for sterilizer area
68° to 73° temp 30 to 60% humidity 10 Air changes positive pressure
What is the recommended release temperature for steam sterilizer packs
70- 80 degree
Parameters for sterilizer access area
75° to 85° 10 air changes negative pressure
How are microorganisims killed for EO
Alkylation
What is the package choice for dry heat sterilization
Aluminum foil
