A Novel Patient Monitoring System Using Photoplethysmography and IOT in the Age of COVID-19

Abstract

COVID-19 has hit the world like a storm and brought the healthcare systems along with entire economi es down with it. In the age of IOT, there has been an increase in the use of interconnected sensors for automating many day-to-day tasks. Internet of Medical Things or IOMT is a subdiscipline of IOT that can alleviate the stress on the medical institutions during this pandemic and allow for remote patient monitoring at a lower cost. This paper will focus on an Android App that will measure the Heart Rate and Oxygen S aturation (also known as S PO2) of COVID-19 patients and the general public using photoplethysmography and IOT. The edge provided by our proposed model is the wide availability of a large range of sensors and microcontrollers and it's relatively low cost as compared to the current architecture being used. Another advantage of our approach is generation of data that can be used for further understanding and research. The app will then be upgraded to connect to multiple sensor devices connected to the same microcontroller module and receive data from those, hence creating a fully functional interface for complete health monitoring of patients as well as the general public at a minimal cost.

COVID-19 detection using a model of photoplethysmography (PPG) signals

“…in a recent partially prospective, observational study used the PPG signal to confirm the presence in a large number of patients of PPG dropout threshold and PPG amplitude abnormalities [33] . Other studies have verified how PPG technology can be used for monitoring, even remotely, patients with COVID-19 at different levels of severity [34] , [35] , [36] .…”

Design And Development Of Spo2, Bpm, And Body Temperature For Monitoring Patient Conditions In Iot-Based Special Isolation Rooms

“…Currently, many tools for monitoring the patient's physiological state have been developed by conducting significant diagnostic tests with measurements of BPM, SpO2, and IoT-based patient body temperature. [6], [7], [8], [9], [10], [11], [12], [13], [14]. The implementation of the Internet of Things (IoT) in the design of monitoring tools for BPM, SpO2, and patient body temperature provides many benefits including facilitating the performance of Health Workers to monitor body conditions, diagnoses, and prevent patient emergencies remotely in realtime, continuously and requires low energy.…”
