A process that eliminates all viable microorganisms including the most resistant forms. The definition is categorial and absolute.
Sterilization
devoids all viable microorganisms, or it has some level of contamination.
sterilization
is the Probability of a microorganism surviving on an item subjected to treatment is less than one in 1 million.
sterility assurance level
what is the probability of a microorganism surviving on an item subjected to treatment?
less one in 1 million
Generally, a less lethal process than sterilization.
disinfection
elimination of nearly all recognized pathogenic
microorganisms
disinfection
is a procedure that reduces the level of microbial
contamination
disinfection
high-level disinfection differs from chemical sterilization by its lack of _________ power or the lack of chemical disinfectants to kill bacterial

In 1972, Dr. Earl Spaulding proposed a system for classifying liquid chemical germicides and inanimate surfaces.
Spaulding classification
when was spaulding classification proposed? and who proposed it?
1972, Dr. Earl Spaulding
from the Spaulding classification under the inanimate surface categories, these are Instruments or devices that are exposed to normally sterile areas of the body require sterilization.
critical
what are the inanimate surface categories in Spaulding classification?
Critical, semi-critical, non-critical
from the Spaulding classification under the inanimate surface categories, these are Instruments or devices that touch skin or come into contact with person only indirectly
non-critical
from the Spaulding classification under the inanimate surface categories, these are Instruments or devices that touch mucous membranes may either sterilized or disinfected.
semi-critical
inanimate surfaces that are considered critical are requires what process of cleaning? how about semi-critical? non-critical?
Critical- Sterilization
semi-critical - sterilization or disinfection
Non-critical - intermediate level disinfection, sanitized with low level disinfectant or soap and water
