Analysis of a nurse call system implementation using a wireless sensors network

Abstract:

A nurse call system is used to improve the patient assistance and to make efficient use of the hospital staff. The aim of this project is to analyze the use of a Wireless Sensor Network (WSN) that works as an alarm center, emergency calls and as abnormal environmental parameters. The system allows knowing the temperature, relative humidity (RH) and the level of CO2, in different hospital areas, which will ease the preventive management of environmental emergencies. Moreover, the system enables to know the response time and the nurses’ attention, providing statistics that will help to control the efficiency of the hospital staff and the quality level of the care provided. During the functionality testing made to the developed nurse call system, the results are encouraging, the reached data transmission reliability is 93%, from the farthest room to the nursing center. The system successfully provides relevant data to the environmental parameters of the hospital, the attention time and the staff response are successfully controlled. In the testing phase, it was also observe that the system is highly scalable, due to the easy integration of new devices to the network, thanks to the use of the ZigBee protocol and to the mesh topology. The implementation of this system is simple because it is wireless and it does not cause damage to the physical structure of the health center.
