What about wireless phone interference with medical
equipment?
Radio Frequency (RF) energy from wireless phones can interact
with some electronic devices. For this reason, the FDA helped
develop a detailed test method to measure Electro Magnetic
Interference (EMI) of implanted cardiac pacemakers and
de
fi
brillators from wireless telephones. This test method is
now part of a standard sponsored by the Association for the
Advancement of Medical Instrumentation (AAMI). The
fi
nal 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
de
fi
brillators 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 speci
fi
es 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.
