  • Spaulding Classification System

    classification used by CDC and AAMI to classify patient care equipment

  • Spaulding Classification: Critical Items

    items that enter sterile tissue or blood vessels: surgical instruments, needles, implants

  • Spaulding Classification: Semi-Critical Items

    items that touch mucous membranes: laryngoscopes, tracheal tubes

  • Spaulding Classification: Non-Critical Items

    items that touch skin: stethoscopes, thermometers

  • bacterialcidal

    substance that kills bacteria

  • disinfectant

    chemicals that kill most pathogens, NOT spores

  • disinfection

    destruction of most pathogens, NOT spores

  • sterilize/sterilization

    completely killing all microorganisms

  • HLD

    high level disinfection: destruction of vegetative microorganisms, but NOT spores

  • Low-level disinfection

    destruction of some vegetative forms of bacteria

  • Intermediate-level disinfection

    destruction of viruses, fungi and vegetative bacteria

  • organic materials

    matter containing oxygen, carbon, and hydrogen from living organisms

  • contact/wet contact

    disinfectants must make direct contact with surfaces to be effective

  • exposure time

    disinfectants have a set amount of contact time to be effective

  • Quats

    quaternary ammonium compounds: low-level disinfectant incompatible with soap

  • alcohol

    both an antiseptic and disinfectant, needs we contact for a minimum of 5 minutes

  • phenolics

    low to intermediate level disinfectant good for environmental services of hard surfaces

  • chlorine

    intermediate level disinfectant commonly used to treat water and sewage

  • iodophors

    buffered iodine that can be both an antiseptic and disinfectant, can stain

  • Glutaraldehyde

    HLD: used for semi-critical devices, needs to be activated and tested for minimum effective concentration before use

  • MEC

    minimum effective concentration: the percentage of concentration of disinfectant in a solution for the disinfectant to be effective

  • OPA

    ortho-Phthalaldehyde: HLD: used on semi-critical items, no activation required, solution can be re-used

  • hydrogen peroxide

    HLD: broad spectrum can kill MRSA, norovirus, TB, and others

  • Peracetic acid

    HLD: used in automated endoscope reprocessors (AERs)

  • Washer-disinfector

    washing machine that uses thermal disinfection and impingement to clean instruments

  • pasteurizers

    disinfection equipment using 150-170 degree water, requires 30 minute exposure time

  • AER

    automated endoscope reprocessors: disinfects flexible fiber optic endoscopes
