Environmental Monitoring System with Wireless Sensing and IoT Technologies for Intensive Care Units

Abstract

In Honduras, many healthcare centers do not have automated recording and monitoring of the environmental parameters of the rooms. Consequently, these parameters are monitored manually or even go unnoticed by maintenance personnel, due to the lack of the necessary tools for constant monitoring. Temperature, relative humidity, carbon dioxide and the intensity of environmental acoustic noise are the main parameters that will allow the validation of air quality. Thus, a remote monitoring system based on IoT is proposed that allows viewing all these parameters in a centralized and remote way. This system will have a special focus on the intensive care ward, as it is a critical area that requires a high level of monitoring and supervision for its conditions. By experimentation, it allowed tests to be conducted in different environments such as controlled environments, angiography operating rooms and finally the target room, which is the intensive care unit. Sensor data was corroborated by other measurement instruments as well as other similar sensors. By having a centralized monitoring alert system that allows health personnel to allow resources, both human and material, to be directed to more relevant activities within a hospital center.
