Principles of Asepsis and Aseptic Technique Flashcards
(23 cards)
Fomite
inanimate object that harbors microorganisms
Sterile
free of ALL microorganisms
Masks
don’t criss cross
handle by strings or elastics only
Laundry
washed at 160F/50/150 parts bleach
OR ventilation, temp, humidity
15 air exchanges/hr with 3 fresh
68-73F
not less than 50%
Surgical suite
3 areas
unrestricted-street clothes
semirestricted-properly attired personnel
restricted-scrub attire, masks, hats, jumpsuits
Mayo stand
frame with a removable tray
Suction/ESU
last to be turned off
Levels of sterility
critical-enters body tissue under skin (sterile)
semi-critical: in contact with intact skin or mucous membranes (disinfect)
noncritical: skin/mucous membranes away from surgical site
Antisepsis/asepsis
absence of pathogenic microorganisms
Laminar air flow
traps and eliminates 99% of particles larger than .3 micrometers
Standard precautions
formally known as universal precautions
hand washing
occupational exposure
Communicable infection
systemic, bacterial, viral, or fungal infection
spread from one person to another
Airborne contamination
dispersion of fine mist, droplets, or particulate matter into the air
Aseptic technique
prevent microbial contamination of the surgical environment
Spontaneous infection
localized that requires surgical diagnosis and treatment, appendicitis
Endogenous nosocomial infection
sources within the body
intestinal flora escapes abdominal cavity
Sterile technique
sterile field keeps microbes at an absolute minimum
Strikethrough
package gets wet
Implosion
pervious material drops to floor
Tables ___” from wall
18”
Line of demarcation
inside wrapper to 1”
inner edge of heat seal
Unsterile personnel ___’ from sterile areas
1 foot
