Flashcards: SP CH9

classification used by CDC and AAMI to classify patient care equipment

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

items that touch mucous membranes: laryngoscopes, tracheal tubes

items that touch skin: stethoscopes, thermometers

substance that kills bacteria

chemicals that kill most pathogens, NOT spores

destruction of most pathogens, NOT spores

completely killing all microorganisms

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

destruction of some vegetative forms of bacteria

destruction of viruses, fungi and vegetative bacteria

matter containing oxygen, carbon, and hydrogen from living organisms

disinfectants must make direct contact with surfaces to be effective

disinfectants have a set amount of contact time to be effective

quaternary ammonium compounds: low-level disinfectant incompatible with soap

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

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

intermediate level disinfectant commonly used to treat water and sewage

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

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

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

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

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

HLD: used in automated endoscope reprocessors (AERs)

washing machine that uses thermal disinfection and impingement to clean instruments

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

automated endoscope reprocessors: disinfects flexible fiber optic endoscopes
