11. What about wireless phone interference with medical equipment?
Radio frequency 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 ‘compati-
ble’ 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.
