11. 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
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.
