Safety

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

S a

cardiac pacemakers and defibrillators are safe from

f e t

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.
