Abstract
Lack of healthcare or inaccessibility of doctors and caregivers is a major
concern. The increase in COVID-19 patients is putting tremendous pressure on hospital
management in urban areas. Therefore, the development of IoT (Internet of Things)
based patient monitoring systems allows doctors to obtain patient data from remote
locations. The Internet of Things is an evolving technology that takes healthcare to the
next level by providing affordable, reliable, and convenient devices that can be carried
or embedded with patients. There is a growing interest in wearable sensors and medical
devices. Therefore, wearable monitoring systems will take patient monitoring to a new
level. The IoT allows various devices to be connected over the Internet. Data is
collected using sensors and sent to the cloud via IoT channels, where both patients and
doctors can access the data (real-time and historical) through a variety of devices. Any
deviations from the norm will result in alerts being sent to both doctors and patients.
This enables doctors to monitor a large number of patients at once.
