the 3 environmental control areas in the surgical department?
-unrestricted
-semi-restricted
-restricted
three types of procedure rooms
-examination room
-procedure room
-operating room
examination room/procedure room
-unrestricted area
-requires sterile intruments or high-level disinfection
-does not need exact environmental control requirements
the operating room
-electrical outlets
-suction outlets
-gas outlets
-monitors and views boxes
-computers
-furniture
-cabinets
-lights
-booms
-doors
-environmental controls
back table
-creates a sterile field
-CST arranges the sterile equipment before the surgical procedure.
mayo stands
-used for surgical instruments
ring stand
-has four wheels and can accommodate one or two sterile basins
-basins contain fluids for procedures
kick bucket
-wheeled and maneuvered using the foot
-lined with a biohazard bag
-take sponges by sterile team
linen hampers
ringed stands lined with color-coded bags
which equipment causes electrical hazards
Electrical Surgical Unit (ESU)
also known as cautery box or
bovie unit
what are the three componets to a fire?
heat, ignition source, oxygen
explain fire extinguisher class A
pressurized water and appropriate for fires
-used for solid materials
explain fire extinguisher class B
dry chemical or co2, appropriate for fires involving gas, oil, and flammable liquids
explain fire extinguisher class C
halon
used for laser or electrical fires
the 2 allergic respones of latex and explain them
Type IV- less serious (skin irritation)
Type I - more serious (may lead to respiratory arrest)
explain surgical plume hazard
cauterized or coagulated tissue due to a laser or electrosurgery produces a plume
plume has an offensive odor that can irritate the eyes
anesthetic gases
the machine has a gas scavenging system
this system collects, filters and disperses waste
polymethyl methacrylate
referred to as bone cement,
consist of a liquid and powder mixture used to cement metal prostheses during total joint arthroplasty procedures
the vapors are toxic
formalin
used to perserve tissue specimens
the liqid chemical produces vapors which can be toxic
it is carcinogen, mutagen and is noxious to the liver
ethylene oxide
used to sterilize heat-sensitive surgical equipment
EtO is known to be carcinogenic and highly mutagenic
glutaraldehyde
known as Cidex used to disinfect and sterilize instruments
the fumes can hurt the eyes and mucous membranes
Peracetic Acid
has high oxidizing potential and is used as an antimicrobial agent.
isolyzer
used to solidify blood in suction canisters
chemotherapy
agents are called cytotoxic or antineoplastic drugs
chemicals kill or inhibit cancer cell growth
betadine
used to disinfect skin before and after surgery
contains elemental iodine
alcohol
highly flammable in the environment
benzoin
protects patients skin from irritation ancts as an antiseptic before the application of skin barriers and adhesives
what is spill kit used for
absorbs biological and chemical spills
what is the eyewash station used for
in case of eye exposure to any hazardous substance
OSHA
establishes standards that dress issues around workplace safety to protect healthcare workers
NIOSH
branch of the CDC, agency tends to be more research oriented in establishing permissible exposure limits
ANSI
promotes and facilitates consenus standards in technical fields
ASTM
an organization composed of industry experts provide voluntary consensus standards for medical equipment
AAMI
establishes standards that include electrical safety, sterilization, levels of device safety, and use of medical devices
NFPA
aims to reduce the occurrences of fires
