Publisher Summary This chapter discusses the threat posed by intentional and unintentional electromagnetic interference (EMI) to the integrity of health care organizations. EMI has the ability to degrade or totally disrupt the health care delivery. EMI can be natural (static electricity or lightning) or man-made.

Harmonics and Electromagnetic Interference [PDF]
, 2000 Electrical interference is an unwanted consequence of power electronics apparatus. This issue is addressed by highlighting the main controlling factors and by developing equations that assist in quantifying the severity of the problem. Both themes are directed at power frequency harmonics: they are also applied to electromagnetic interference where, in

Antennas and electromagnetic interference
Ninth International Conference on Antennas and Propagation (ICAP), 1995The objective of the paper is to present a general model for the coupling of antenna fields to lossy in-circuit interconnects such as striplines and interequipment interconnects such as braided coaxial cables, when the line is placed in the near-field zone of the antenna and the fields are highly non-uniform.

Electromagnetic interference in critical care
Journal of Critical Care, 2006Mobile communication and wireless data transmission are playing an increasing role in health care. Reports describing medical device malfunction related to cellular phones have raised awareness about the problem of electromagnetic interference. Although initial institutional responses were to ban cellular devices in hospitals, these restrictions are ...

Publisher Summary This chapter discusses electromagnetic interference (EMI), which is broadly divided into two types: interference and susceptibility. It does not focus on interference generated by equipment, except where that interference is self-generated, but concentrates on susceptibility—what causes it and what can be done about it.

Electromagnetic interference: a tutorial
1996 IEEE Aerospace Applications Conference. Proceedings, 2002The treatment of electromagnetic interference (EMI) problems is perceived by many engineers as a generally unscientific, hit or miss, procedure. The intent of this tutorial is to present a practical, understandable, and straightforward approach to solving interference problems.

Electromagnetic interference risk analysis
IEEE Engineering in Medicine and Biology Magazine, 2008Daily mitigation of and planning for intentional or unintentional EMI should be a part of a medical facilities ongoing spectrum management just as annual condition and risk assessments are performed at other facilities. A reasonable supply of spare electronic components should be stored safely on site and readily available (network switches, wireless ...

Electromagnetic Interference in Implantable Pacemakers*
Pacing and Clinical Electrophysiology, 1978The inhibited pacemaker (VVI or AAI) has become the most popular in recent years because of its ability to combine a physiological advantage with economical current consumption in cases with spontaneous activity. One of its disadvantages is its sensitivity to external electromagnetic interference. Though today's pacemakers possess, effective protection

Electromagnetic Interference (EMI)
2010Radiated emissions in high-speed DSP systems are caused by fastswitching currents and voltages propagating through printed circuit board traces. As DSP speed increases, printed circuit board traces are becoming more effective antennas, and these antennas are radiating unwanted energies that interfere with other circuitry and with other systems located ...

Electromagnetic Interference and Compatibility
2014EMI requires a (1) source of energy, (2) a receptor or victim circuit or system, and (3) some coupling path for the energy to get from one place to the other. If there is no energy source, there is no EMI, and if there is no coupling path, there is no EMI.
