Evidence that mobile phones can interfere with vital intensive care equipment has been strengthened. More than half the hospital ventilators tested by Dutch researchers stopped working properly when a mobile was switched on nearby.
A total of 61 different medical devices were tested, and the majority could be affected by the presence of a mobile. In particular, nine intensive care ventilators were checked, and seven of these could be “influenced” by mobiles.
Other devices which suffered problems were dialysis machines, external pacemaker machines, feeding pumps and even air humidifiers.
