Infection Control Flashcards
(47 cards)
render an area, device, item, or material safe to handle that is reasonably free from a risk of disease transmission
decontamination
a process of cleansing an object or a substance
decontamination
act or process, physical or chemical that destroys or eliminates all forms of life, especially microorganisms
sterilization
less lethal process than sterilization
disinfection
is absolute
sterilization
elmination of nearly all recognized pathogenic microorganisms but not necessarily all microbial forms
disinfection
most common physical method of sterilization
incineration
decontaminate potentially infectious materials before disposal or reuse
biosafety process
in incineration, materials are burned to ashes at a temperature of
870-980 degree C
15 psi, steam under pressure for heat stable object
moist heat
the fastest and simplest, also most effective
moist heat
biological indicator of moist heat
bacillus steatothermophilus
moist heast uses an equipment called __ which is like a large pressure cooker
autoclave
most common autoclave
gravity displacement type
moist heat for media, liquids, and instruments
121 C (250F) at 15 psi for 15 minutes
moist heat for infectious medical waste
132 C for 30-60 minutes
contains bacterial spores suspended in a growth medium, incubate at 35 C
sealed ampules
no color change of the medium (purple)
spores were killed
there is acid production that causes color change to the medium
Spores were not killed
What should not be autoclaved!
corrosive materials
radioactive materials
‘alternate heating, incubation and heating
Fractional sterilization
Tyndallizarion
100° C, 30 minutes for 3 days
inspissation
76-80°C, 2 hours for 3 days
Temp for dry heat
100-180 C for 1.5 - 3 hours
