What is cavitation in ultrasonic cleaning?
Answer: Formation and implosion of microscopic bubbles that dislodge soil from surfaces
Ultrasonic cleaners use high-frequency sound waves to create cavitation, which dislodges soil from instrument surfaces.
Why must the lid be closed on an ultrasonic cleaner during operation?
Answer: To prevent aerosolization of infectious contaminants
Cavitation generates aerosols containing potentially infectious microorganisms, so the lid must stay closed.
What minimum free chlorine concentration is used for intermediate-level surface disinfection in decontamination?
Answer: 500 ppm
500 ppm free chlorine (1:100 bleach dilution) is recommended for intermediate-level disinfection of contaminated surfaces.
What PPE is required for decontamination area personnel?
Answer: Scrub attire, fluid-resistant gown, utility gloves, face shield or goggles with mask, and hair cover
Multiple layers of protection are needed: fluid-resistant gown, heavy-duty gloves, face protection, and hair covering.
How often should washer-disinfector cleaning efficacy be verified?
Answer: At least daily using cleaning indicators or protein residual tests
Cleaning efficacy should be verified at least daily using commercial cleaning verification devices.
What happens when an instrument's manufacturer IFU conflicts with facility cleaning protocol?
Answer: Follow the manufacturer's IFU as it takes precedence
The manufacturer's IFU takes precedence because they have validated the specific cleaning requirements.
