To determine whether cellular telephones used in a normal way would cause interference with medical devices located in patient care areas of hospitals.
Two cellular telephones from different cellular carriers were tested in various patient care areas between February 15, 2006, and June 29, 2006. To monitor the medical devices and equipment in the patient care areas during testing, we observed the device displays and alarms.
Interference of any type occurred in 0 of the 75 patient care rooms during the 300 tests performed. These 300 tests involved a total of 192 medical devices. The incidence of clinically important interference was 0% (95% confidence interval, 0%-4.8%).
Although cellular telephone use in general has been prohibited in hospitals because of concerns that these telephones would Interfere with medical devices, this study revealed that when cellular telephones are used in a normal way no noticeable interference or Interactions occurred with the medical devices.
确定以正常方式使用的移动电话是否会对医院患者护理区域内的医疗设备造成干扰。
2006年2月15日至2006年6月29日期间，在不同的患者护理区域对两部来自不同移动电话运营商的移动电话进行了测试。为了在测试期间监测患者护理区域内的医疗设备和器材，我们观察了设备的显示屏和警报。
在进行的300次测试中，75间患者护理病房中均未出现任何类型的干扰。这300次测试总共涉及192台医疗设备。具有临床意义的干扰发生率为0%（95%置信区间，0%-4.8%）。
尽管由于担心移动电话会干扰医疗设备，医院通常禁止使用移动电话，但本研究表明，以正常方式使用移动电话时，不会对医疗设备产生明显干扰或相互作用。
