knob sterilize
(wait for correct temperature and pressure) set timer to 20 min
ultrasonic cleaner
a device that loosens and a removes debris with the use of sound waves traveling through a liquid
chemical vapor sterilizer
a piece of equipment that is used for sterilizing by means of hot formaldehyde vapors under pressure
autoclave
a piece of equipment that is used for sterilizing by means of moist heat under pressure
dry heat sterilization
a piece of equipment used for sterilization by confirming that all spore-forming microorganisms have been destroyed
sterilization
a process intended to kill all microorganisms and is the highest level of microbial destruction(spores)
endospore
a resistant, dormant structure that is formed inside of some bacteria and can withstand adverse conditions
sterilant
an agent capable of killing microorganisms
static air
an example of dry heat sterilization is
multi-parameter indicator
an indicator that reacts to time, temp, and the presence of steam
critical instrumnet
an instrument used to penetrate bone or soft tissue
disinfection
contact time of less than 10 hours of chemical sterilization
no
do process integrators indicate sterility
process integrator
dot inside
process indicator
dot outisde
through percutaneous injury or contact with mucous membranes of the eyes, nose, or mouth
how can exposure occur
disinfect it
how do you clean noncritical instruments
flush water through it for 20-30 sec
how do you prepare a high-speed handpiece for sterilization
with sterile water
how do you rinse instruments that have been processed in a liquid chemical sterilant
with cold water
how do you rinse instruments that have been processed in an ultrasonic
on a tray or plastic bin
how do you transport instruments
5 min for saliva and 15 min for surgery
how long does it take to clean in the ultrasonic
weekly
how often should biological monitoring be tested
once a day
how often should the solutions be thrown away
process indicators
identity instrument packs that have been exposed to a certain temperature
they should be placed in a holding solution
if the instruments cannot be processed immediately what should be done with them
the monitoring service immediately gives a phone call to the dental office
if the spore test is failed
noncritical
instruments that come in contact wih the skin only
semicritical
instruments that come in contact with oral tissues but do not penetrate it or bone
FDA approved
kitchen dishwashers cannot be used to pre-clean instruments because they're not
physical monitoring
looking at the gauges and readings
event related packaging
means that it is assumed the contents of a package will remain sterile indefinitely unless the packaging is complete
knob vent
open chamber slightly after a few minutes allows instruments to dry
rinse with water disinfected and rinsed again and dried
process of ultrasonic cleaner
chemical sterilization
requires 10 hours of contact time; anything less than 10 hours is disinifection
use of lubrication
rusting of instruments can be prevented by
from dirty to clean to sterile to storage without ever doubling back
single loop
single parameter indicator
tapes, strips, and tabs with heat sensitive chemical change when exposed to a certain temperature
single loop
the basic rule of the workflow pattern is an instrument-processing area
critical, semicritical, and noncritical
the instrument classifications used to determine that the method of sterilization and disinfection
use life
the length of time that a germicidal solution is effective after it has been prepared for use
clean area
the sterilization center where contaminated items are brought for precleaning
knob fill
to line at bottom of chamber with distilled water
biological monitoring
verifies sterilization by confirming that all spore-forming microorganisms have been destroyed
biological indicator
vials or stripes, also known as spore tests, that contain harmless bacterial spores and are used to determine whether a sterilizer is working
sound waves
what does an ultrasonic use to work
critical and semicritical
what instruments do you have to sterilize
instruments will not rust
what is the major advantage of chemical vapor sterilization
biological monitoring
what is the only way to deteremine sterilization
heavy gloves
what is worn while handling instruments
steam and chemical vapor
what type of heat sterilization is apporpiate for high speed handpieces
goggle-type eyewear
what type of personal protective equipment is necessary when one is processing instruments
inability to wrap items
what's the primary disadvantage of flash sterilization
250 F for 30 min
whats the temperature and time for sterilization
hand scrubbing, ultrasonic cleaning, and with the thermal washer and disinfector
which are the methods of precleaning
physical, chemical, and biological
which is the form of sterilization monitoring
hand scrubbing
which method of precleaning instruments is least desirable
they will cause holes in the packaging
why pins staples and paper clips are not used on instrument packaging
maintain sterility and organization
why should instruments be packaged for sterilization
