This study evaluated whether a lightweight Mu-metal and copper mesh shielded helmet with EMF channels could reduce external electromagnetic interference enough to measure cortically generated EMF using non-contact induction sensors without a shielded room. In five volunteers performing motor, verbalization, and…

This study tested whether radiofrequency emissions from a ringing GSM mobile phone affect home blood glucose monitor readings. Among 45 female nondiabetic students, the group measured in the presence vs absence of a ringing phone showed larger changes between two readings than a repeat-measurement control group…

This in vitro study tested electromagnetic compatibility between passive RFID readers and 15 pacemakers plus 15 ICDs across 134 kHz, 13.56 MHz, and 915 MHz bands. EMI reactions were common with low-frequency RFID and rare with high-frequency RFID, while no reactions were observed with ultra-high-frequency or…

This study tested electromagnetic interference from GSM and CDMA mobile phones placed one foot from ICU devices (syringe pump, mechanical ventilator, bedside monitor) in off, standby, and talk modes. EMI was observed for the syringe pump in talk mode, with a mean 2.66 ml variation between calculated and delivered…

Jan 1, 2008
This engineering study updates a prior (2005) survey on electromagnetic interference (EMI) affecting infusion pumps and extends testing to DECT phones and WiFi terminals. It reports a reduced failure rate for GSM phone exposure compared with 2005 (58% to 30%). The authors report that WiFi and DECT did not pose a real…
