Mobile phones do not appear interfere with hospital equipment, a US study has shown.
The research looked at how two different mobile phones from different service providers affected medical equipment between February and June last year.
Researchers observed displays and alarms on medical devices and equipment in the patient care areas during testing.
They conducted 300 tests on 192 medical devices in 75 patient care rooms and found the incidence of clinically important interference was 0%.
The authors concluded that although mobile phones were banned in hospitals because of interference concerns, when phones are used normally no noticeable interference or interactions occurred with medical devices.
