Unit 3a; Facilities Flashcards
what is a barrier/containment facility
facility that takes precautions to keep disease agents out and/or to keep disease agents from getting out
what is a conventional facility
no special precautions taken against intro of disease
facility design usually used for smaller facilities
conventional
facility design usually used for larger animals (D/C, farm)
conventional
facility design usually used for small animals like rodents
barrier/containment facility
precautions taken by barrier/containment facilities
PPE, showers, autoclave/disinfect entering items, “clean hallway” and “dirty hallway”
facility design usually used for breeding and experimental animal colonies
barrier/containment suite
important features of animal room constuction
waterproof nonslip floors, slotted drains, slopped floor towards drain, walls/floors made of concreted or other sealed material, no cracks/chipped paint, recessed ceiling light fixtures and power outlets, selfclosing doors w/ kickplates
positive pressure v neg pressure rooms
pos= higher pressure, air flows out neg= lower pressure, air flows in
examples of pos and neg pressure rooms
pos= surgery suites, barrier rooms (avoid contamination entering room) neg= quarantine rooms, waste rooms (avoid contamination leaving room)
what is macroenvironment v microenvironment
macro= environment in the animal rooms micro= environment in individual cages
what is the primary concern when referring to the research animals environment?
comfort and experimental conditions
what is the thermoneutral zone (TNZ) in which animal rooms are maintained
temp range where animal does not need physical or mechanical mechanisms to control heat production or loss (no energy expended), also less stress is produced
breeding rooms should be at the high or low end of temp range?
why?
high; neonates cannot thermoregulate
post-op recovery rooms should be at high or low end of temp range?
high
