Packaging used for steam sterilization must be capable of withstanding
high temperatures of? - ANSWER>>250'F - 275'F (121'C - 135'C)
Process in which a device is actively subjected to moving air; Ex items
being sterilized with ethylene oxide gas. - ANSWER>>Aeration
Microorganism that requires the presence of air or oxygen for growth. -
ANSWER>>Aerobe
Packaging choices for dry heat sterilization must be able to tolerate? -
ANSWER>>2-3 hours exposure time and temperature of 320'F - 400'F
(160'C - 204'C)
Packaging choices for gas plasma sterilization must be able to tolerate? -
ANSWER>>A deep vacuum draw without absorbing the sterilant,
interrupting the cycle, or damaging the contents.
Broad term describing a wide variety of plain-weave cotton/polyester
fabrics having approximately 140 threads per square inch. -
ANSWER>>Muslin
The condition that arises when steam is at a temperature which exceeds
that of saturated steam at the same pressure. - ANSWER>>Superheating
All linen packaging materials should be held at? - ANSWER>>Room
temperature (64'F to 72'F; 18'C to 22'C) and at a relative humidity ranging
from 35% to 70% for a minimum of two hours prior to sterilization.
, A non-woven packaging material which is the most popular flat wrap. -
ANSWER>>SMS (spunbond-meltblown-spunbond)
Sterility Maintenance Covers - ANSWER>>Should be at least 2 to 3 mils
thick. The over -wrap should be clearly marked as a "dust cover" or
"protective wrap" to prevent its use as a part of the sterile field.
All packaging material should be held at - ANSWER>>Room temperature
(67'F to 72'F; 18'C to 22'C) and
at a relative humidity ranging from 35% to 70% for a minimum of two hours
before sterilization

instruments sets - ANSWER>>25 pounds
Sterility (time-related) - ANSWER>>A package is considered sterile until a
specific expiration date is reached
Sterility (event-related) - ANSWER>>Items are considered sterile unless
the integrity of the packaging is compromised (damaged) or suspected of
being compromised (damage) regardless of the sterilization date. This
sometimes is referred to as ERS (Event-Related Sterility)
Point of Use Processing - ANSWER>>That which allows when a medical
device is processed immediately before use, and/ or close to the patient
are area
Flash sterirization - ANSWER>>The process by which unwrapped
instruments are sterilized for immediate use when an emergency situations
arises
AAMI - ANSWER>>Association for the Advancement of Medical
Instrumentation
