Development of an IoT Based Health Monitoring System for e-Health

Abstract

Healthcare monitoring system in hospitals and other health institutes has increased significantly. In recent days healthcare monitoring systems with new technologies are becoming of great concern to countries all over the world. Nowadays IOT (internet of things) is such an emerging technology. Iot consists of various sensors and communication devices which are necessary tools for IOT based health monitoring systems. Among the various applications that Internet of Things (IoT) facilitated to the world, Health care and Health monitoring applications are most important. It also responded if any medical emergency was needed. IoT (Internet of Things) has brought a remarkable approach in healthcare during the global pandemic. The remote health surveillance monitors certain parameters of a patient using digital technology and allows a correct evaluation of health right at home. This brilliant internet revolution has not only minimized patient movement during COVID but also ensured smart healthcare for all ages. IoT heads to set up a strategic connection between the patient & the doctors. The goal is to track the important health parameters such as - Blood pressure, heart rate, blood glucose level etc. and evaluate the data to figure out any sort of medical emergency. From diagnosing heart disease to finding ICU bed availability in the nearest hospitals, digital technology is all set to assist. Using certain medical sensor devices & web-based apps, the health data is passed to the portal from where concerned doctors can provide medical assistance. The data collection, transmission & visualization can use a smartphone as a hub, thus making the operation smooth & flexible. It is the most practical & economical solution to people of all ages while avoiding direct contact & preventing the spread of the virus. The wearable real-time health tracking devices privilege the elder citizen through continuous monitoring while ensuring immediate measures in case of emergency. In this paper, a review of IoT based smart health monitoring systems is presented. The latest innovative technologies used for IoT based smart health monitoring systems with their benefits and challenges have been discussed. This review's goal is to effectively and continuously monitor the multiple patients in a hospital ward and as well as remotely located patients so that it will ultimately reduce hospital operating costs, all other communication costs and improve the quality of health service.
