. What about wireless phone interference with medical
equipment?
radiofrequency energy (rF) from wireless phones can interact with
some electronic devices. For this reason, the Fda helped develop
a detailed test method to measure electromagnetic interference
(EMI) of implanted cardiac pacemakers and defibrillators from
wireless telephones. this test method is now part of a standard
sponsored by the association for the advancement of Medical
instrumentation (AAMI). The final draft, a joint effort by the FDA,
medical device manufacturers, and many other groups, was
completed in late 2000. this standard will allow manufacturers
to ensure that cardiac pacemakers and defibrillators are safe
from wireless phone eMi. the Fda has tested hearing aids for
interference from handheld wireless phones and helped develop
a voluntary standard sponsored by the institute of electrical
and Electronic Engineers (IEEE). This standard specifies test
methods and performance requirements for hearing aids and
wireless phones so that no interference occurs when a person
uses a 'compatible' phone and a 'compatible' hearing aid at the
same time. this standard was approved by the ieee in 2000.
the Fda continues to monitor the use of wireless phones for
possible interactions with other medical devices. should harmful
interference be found to occur, the Fda will conduct testing to
assess the interference and work to resolve the problem.
