HAIs and Equipment Flashcards
describe alkaline cleaning products
they dissolve protein and fat but are corrosive
what should reports on results of monitoring include?
Daily BI testing for steam sterilization.
BI testing of every load for EO and other gaseous chemical sterilants.
BI testing of every load with implants.
Number of positive BI results and what actions were taken.
How many times implants were released before BI results were known.
How often IUSS was performed.
what are some no touch methods of environmental surface cleaning?
-uv light
-hydrogen peroxide
-copper
describe copper surface technology
interrupt the cellular metabolic activity of microorganisms and inhibit growth. Copper-infused surfaces can inhibit bacterial growth on environmental surfaces and decrease the accumulated bioburden over time in occupied patient rooms.
continuous disinfection
in general patients settings how should flowers and plants be handled?
Limiting flower and plant care to staff with no direct patient contact.
Advising healthcare staff to wear gloves when handling plants.
Washing hands after handling plants.
Changing vase water every two days and discharging the water into a sink outside the immediate patient environment.
Cleaning and disinfecting vases after use.
describe rules for racking in food storage areas
-6 inches above floor with slats for air flow
-at least 2 inches from outside walls
-shelving that allows bottom floor and walls to be cleaned
what are the 5 stages of the vaccine cold chain?
Vaccine manufacturing
Vaccine distribution
Vaccine delivery to provider
Vaccine storage at provider
Vaccine administration
What is the difference between a centralized and decentralized HVAC system
A centralized HVAC system uses an air-handling unit, usually on the roof or in a mechanical room, to move air throughout the facility using ducts.
A decentralized HVAC system typically uses individual fan-coil units to bring air in from outside of the facility and mix it with recirculated air inside the room.
describe ACH
The total number in patient rooms should be 6 ACH.
Operating rooms require a minimum 3 ACH and a total of 15 ACH,
while an airborne infection isolation room (AIIR), such as for bronchoscopy, requires a minimum 2 ACH and a total of 12 ACH.
Peak efficiency for particle removal in an AIIR occurs between 12 and 15 ACH.
describe air pressure balancing
describes the pressure relationships with respect to the surrounding area or corridor. These relationships can be positive (excess air supply in the room), negative (air drawn into the room), or neutral.
describe ASHRAE’s system for rating filters based on the size of microns you fitler
This measure of minimum efficiency reporting values (MERV) uses a scale of 1 through 16. The MERV system rates filter effectiveness using the percentage of efficiency for three ranges of particulate sizes: .30 to 1.0 microns, 1.0 to 3.0 microns, and 3.0 to 10.0 microns. Filters have higher efficiencies when filtering out larger particles
give example of MERV rates for filtering particles 1.0 to 3.0 size
MERV 8—20%
MERV 13—85%
MERV 15—90%
MERV 16—95%
what is the recommended temp and humidity for rooms?
68-75F and 30-60% humidity
True or false. Hospital potable water must have < 1 coliform colonies per 100 mL of water
true
ASHRAE recommends cold water be stored below ___, hot water above __ and recirculate at___
68F; 140F; 124F
