Influence of Mobile Terminals for GSM, GPRS and UMTS on 22 Medical Apparatuses
report
This interference study was performed on 22 medical apparatuses selected by the St. Antonius Hospital at Nieuwegein, The Netherlands. The selected medical apparatuses were seen as critical for patient safety. The medical apparatuses were tested at susceptibility for GSM, GPRS and UMTS signals. These signals were transmitted close to the medical apparatuses at maximum power levels as applicable according to the GSM, GPRS and UMTS standards. The medical apparatuses were placed in the hospital environment. They were fully active during testing but they were not connected to patients for obvious reason. The tested medical apparatuses were 4 Monitors, 3 Pumps, 3 Incubators, 2 Dialys Machines, 2 External (Temporary) Cardiac Pacemakers and others. All medical apparatuses were tested when functioning. Where relevant, tests were performed both with an apparatus powered from the mains and powered from its internal accumulator. The separation distance was determined. This is the distance to the point in space most far from the apparatus where it could just be disturbed. At a found disturbance position, transmission was realised during several tens of seconds.
