Study on the influence of wireless communication technology on sensitive medical equipments In this paper we studied the influence of electromagnetic wireless communications traffic on sensitive medical equipment used in intensive care units. We have identified the main sources of disruptive electromagnetic field existing in a neonatal intensive care unit and studied the influence of wireless communication systems type GSM and DECT 900 on the main operating parameters set to a neonatal mechanical ventilator. After studies we observed that the important parameters used in assisted mechanical ventilation such as expiratory volume, inspiratory pressure, expiratory pressure, mean pressure and tidal volume suffer significant changes when wireless communication disturbing source is at walking distance of sensitive medical equipment.
