“…This minimum distance of separation is where the interference started to take place. According to [31][32][33], it is uncommon for EMI affairs to occur at distances greater than 1 m. Surrounding environment of the hospitals such as building factors and other facilities may influence the degree of EMI [34,35].…”

The application of wireless technology in healthcare is increasing, not only it enhances the quality of patient care and patient mobility, but also it leads to accurate clinical decisions making. However, the electromagnetic energy emitted by the wireless transmitter devices may affects the operation of the medical equipment, especially those in close proximity with one another. In this study, we investigated the wireless technology that has minimal electromagnetic interference on the medical appliances and identified the characteristics of that particular wireless technology. From this review study, the establishment of wireless techniques in healthcare environment depends on the wireless frequency band, the wireless transmitter output power, distances between the wireless devices and the medical equipment, and also the surrounding environment of the hospitals.

Background and Aims:To observe the effects of mobile phone use in the vicinity of medical devices used in a critical care setting.Subjects and Methods:Electromagnetic interference (EMI) was tested by using two types of mobile phones – GSM and CDMA. Mobile phones were placed at a distance of one foot from three medical devices – syringe pump, mechanical ventilator, and the bedside monitor – in switch off, standby, and talking modes of the phone. Medical devices were observed for any interference caused by the electromagnetic radiations (EMR) from the mobile phones.Results:Out of the three medical devices that were tested, EMI occurred while using the mobile phone in the vicinity of the syringe pump, in the ‘talk mode.’ The mean variation observed in the calculated and delivered volume of the syringe pump was 2.66 ml. Mechanical ventilator did not show any specific adverse effects with mobile phone use in the one-foot vicinity. No other adverse effects or unexplained malfunctions or shutdown of the syringe pump, mechanical ventilator, or the bedside monitor was noted during the study period of 36 hours.Conclusion:EMI from mobile phones have an adverse effect on the medical devices used in critical care setup. They should be used at least one foot away from the diameter of the syringe pump.

“…The use of mobile phones for intrahospital communication, however, has been hampered by worries regarding electromedical interference [35,36]. Studies now suggest that electromedical interference may be less of a problem than previously suggested and that the zone of risk for electromedical interference is limited to 1 metre or less around susceptible equipment [37-39]. …”

The Omagh bombing in August 1998 produced many of the problems documented in other major incidents. An initial imbalance between the demand and supply of clinical resources at the local hospital, poor information due to telecommunication problems, the need to triage victims and the need to transport the most severely injured significant distances were the most serious issues. The Royal Group Hospitals Trust (RGHT) received 30 severely injured secondary transfers over a 5-hour period, which stressed the hospital's systems even with the presence of extra staff that arrived voluntarily before the hospital's major incident plan was activated. Many patients were transferred to the RGHT by helicopter, but much of the time the gained advantage was lost due to lack of a helipad within the RGHT site. Identifying patients and tracking them through the hospital system was problematic. While the major incident plan ensured that communication with the relatives and the media was effective and timely, communication between the key clinical and managerial staff was hampered by the need to be mobile and by the limitations of the internal telephone system. The use of mobile anaesthetic teams helped maintain the flow of patients between the Emergency Department and radiology, operating theatres or the intensive care unit (ICU). The mobile anaesthetic teams were also responsible for efficient and timely resupply of the Emergency Department, which worked well. In the days that followed many victims required further surgical procedures. Coordination of the multidisciplinary teams required for many of these procedures was difficult. Although only seven patients required admission to adult general intensive care, no ICU beds were available for other admissions over the following 5 days. A total of 165 days of adult ICU treatment were required for the victims of the bombing.
