Electromagnetic interference: causes and concerns in the health care environment.
In the past 15 years there has been a dramatic increase in the number of radio frequency emission sources that have entered medical treatment areas. Personal computers, digital pagers, hand-held radios, cellular phones, and wireless input devices have all become more prevalent in the contemporary clinical environment. Because of the productivity gains these devices promise, it is unlikely that the use of electronic instrumentation and wireless technologies will diminish--in fact greater uses are projected. Along with the benefits these devices provide, they also create a greater opportunity for increased electromagnetic interference among devices. It is important that engineering and professional staff are aware of some of the complex interactions these devices can create. Managing this emerging problem should be a concern for the medical community. Engineering staff should be able to communicate effectively with medical staff, patients, and visitors regarding potential interactions and how to recognize them and mitigate their consequences.
