b. Using ultrasonic
technology, these
units loosen biobur-
den and debris
through a process
called cavitation.
Think of cavitation
as miniature implod-
ing bubbles working
throughout the chamber to attach themselves to bioburden and break
the debris away from internal cannulas, hinged surfaces and other
areas difficult to access with brushing alone.
7. Ultrasonic cleaners are a Class 2 medical device, meaning they
don't require regular
testing as washers and sterilizers do.
a. true b. false
b. Industry recommendations state that you should test ultrasonic
cleaners on a regular basis, meaning every day the unit is in use. As
with any other testing and monitoring in the sterile processing depart-
ment, complete these records with equipment identification, employ-
ee name, date, outcome of the test and any required corrective action.
Ensure each team member has been trained on interpreting the test
results and correctly documenting them in the department records.
