  20. what are the 2 types of heat?
    • moist
    • dry
  21. this type of heat sterilization is done by either boiling or steam under pressure
    kills microbes by coagulating critical cellular proteins
    moist heat
  22. type of heat sterilization that is difficult to control
    longer sterilization pd, kills microbes by protein oxidation
    dry heat
  23. type of moist heat
    only sanitizes at 60C or 140F & higher
    sanitizin can be increased with scrubbing and detergent
    doesnt sterilize
    ex: auto dishwashers/ clothes washers
    hot water
  24. type of moist heat (2)
    rarely used because spores and viruses are not killed @ this temp for long pds of time
    only disinfects
    max temp 212F 100C
    • boiling
    • free flowing steam

    • water vapor
  34. drying kills MOs through ____
  35. what is the one major benefit of dry heat?
    doesnt corrode/dull instruments/needles
  36. what is important to remember about using dry heat and the evaporation process?
    • this basically aersolizes whatever was on those tools.
    • this will increase dispersal of MOs
  37. this method of dry sterilization gives complete destruction of materials that are non-reusable and have no value
    ex: paper drapes
  38. w/ incineration, the material must b completely reduced to ash because if there are clumps ____ may still be present/protected
  39. a hot air oven needs a temp of ____-____C or ____F for ____ hours.
    • 150-170C
    • 340F
    • 3 hours
  40. this method of dry sterilization doesnt dull/corrode metals/sharps
    takes longer/requires higher temp
    paper, cloth, plastic and rubber should not be sterilized this way
    hot air ovens
