Q

sterilization process

A

Process used is dependent on items to be sterilized

  1. Steam –> gravity-displacement
    - Pre-Vacuum
  2. Gas –> Ethylene Oxide
    - Hydrogen Peroxide (STERRAD)
  3. Ionizing radiation–> Cobalt 60
  4. Peracetic Acid–> Steris
  5. Dry heat

Q

exposure cycle, exhaust cycle, drying cycle

A

exposure-reached certain temp.

Q

pre vacuum steam sterilizer

A

270 degrees F - 27 psi (per square inch of pressure) - 4 mins

  • air eliminated from chamber through vacuum force
  • air is replaced by steam
  • *MOST STANDARD
  • quick bc vacuum already took out air

Q

gravity displacement sterilizer

A

250 degrees F - 15psi - 30mins

  • air is heavier than steam
  • steam injected into chamber
  • air is pushed down by gravity and released from chamber through a valve below
  • air replaced by steam

Q

Flash Sterilizer

A

In OR–immediate use items

  • for emergency use
  • only used when NO alternative available
  • UNWRAPPED ITEMS
  • never flash sterilize implants
20
Q

Flash sterilizer parameters

A

metal & nonporous : 270 degrees F/ 3 mins

lumens: 270 degrees F / 10 mins

21
Q

Gas sterilization

A

Ethylene Oxide (toxic) – doesn’t go to high heat

  • penetrating
  • low temp.
  • need humidity/moisture (to be able to hydrate spore)
  • V expensive & time consuming process
  • just as effective but not as practical

*USED FOR SCOPES

22
Q

Aerated

A
  • aerator
  • cycle
  • porosity
  • clean /dry items (toxic residue)
  • items free of lubricating oils (gas can’t penetrate)
  • wrapped items

**items that cant be sterilized with this method are acrylics,pharmaceuticals&glass

23
Q

Gas plasma

A

STERRAD
-hydrogen peroxide–> into vapor
-vapor
scopes,heat and moisture sensitive items, wrapped items

*SHORTER sterilization than Ethyl. Oxide

24
Q

peracetic acid

A

STERIS

  • liquid chem.
  • unwrapped, heat sensitive items
  • *CAN’T use for immersible items
25
Q

ionizing radiation

A

COBALT 60
uses radiation to sterilize
-used for BULK sterilization /COMMERCIAL use
-irradiation

*sponges, sutures, drapes, powders, petroleum & pharmaceutical items

26
Q

high level disenfection

A

GLUTARALDEHYDE/CYDEX

  • NOT STERILIZATION METHOD
  • does not kill spores
  • reprocesses
  • liquid cold soak (20 MINS)
  • items must be clean/dry before soaking
  • used for semi critical items (endoscopes etc)
  • shelf life 14-28 days
  • *items rendered sterile if immersed for 10 hrs
27
Q

what does sterile mean?

A

that microbes & infection are absent

28
Q

bioburden

A

of microbes or organic debris that exist at a given time

29
Q

infection

A

the multiplication of organisms in tissue

30
Q

bacilli are usually found to be in shape of?

A

rods

31
Q

spore

A

dormant structure that some bacteria can form to survive adverse environmental conditions

32
Q

mechanical cleaning

A

physical removal of blood and body fluids or gross debris from and inanimate object

33
Q

should instruments be disassembled prior to cleaning?

A

yepp

34
Q

what catalyst is used to aid in the breakdown of organic material such as blood or tissue?

A

enzyme

35
Q

what is an enzyme usually used as ?

A

a soaking solution

36
Q

example of decontamination unit?

A

ultrasonic washer

37
Q

ultrasonic washer

A

used to remove small organic particles and soil from areas of instruments that are difficult to wash manually

38
Q

non critical items

A

BP cuff, stethoscope ,crutches, bed linens

*just touch the top of skin

39
Q

critical items

A

items that must be sterile
*only touch sterile tissue, incision or needle

catheters,vascular catheters

40
Q

semicritical items

A

*used when entering into mucus membrane or in skin

must be completely free of microorganisms, except bacterial spores

41
Q

indigenous resident microbes

A

microbes that live on skin and inside the human body

42
Q

high level disinfection

A

destroys all forms of microorganisms except bacterial spores

43
Q

cavitation

A

process that further removes particles and debris after the ultrasonic cleaner

44
Q

what is primary advantage of ethylene oxide?

A

it’s ability to penetrate wrappers and to disinfect objects that cannot tolerate heat , moisture or pressure of steam sterlization.
