Abstract

Overcrowding of patients at hospitals is among the challenges of the COVID-19 pandemic. Medical Staff are over tasked and Medical facilities are overwhelmed. Medical Staff in the front line are exposed to risks. The reduction of overcrowding at Hospitals and healthcare centers with the introduction of portable systems for remote monitoring of patients using the Wireless Sensor Networks, specifically for those who are suffering from cardiac diseases is therefore an essential part of COVID-19 pandemic management. Patients with heart failure are at the highest risk during COVID-19 pandemic and the mortality rate of infected patients with heart failure is the highest. The development of a Personal health monitoring device (PHMD) for ECG display, SpO2 and pulse rate (beat per minute) measurements is presented. An Electrocardiogram (ECG) is a graphical presentation of the heart activity over time. The graphical presentation of the ECG can be interpreted, so that normal and abnormal rhythms of the heart can be detected and diagnosed. Pulse oximetry is the non-invasive measurement of the oxygen saturation which is the percentage of SpO2 concentration. It is used for a rapid assessment of a patient’s respiratory function to determine the onset of hypoxemia (oxygen starvation) or COPD (Chronic obstructive pulmonary disease). The aim of the portable healthcare monitoring device is to continuously monitor and measure the patient vital signs in order to detect and prevent a heart attack before it occurs. The sensors convert the detected physiological parameters into electrical signals which will be processed using the digital signal processor (DSP) according to an algorithm. The processed data is transferred to the android application interfaces via serial port Bluetooth communication. The android studio further processes the received data, plots the Electrocardiogram (ECG) graph and displays the SpO2 using algorithms written in java programming language. The android application offers data storage in a cloud server and communication between the patient and the doctor through a chat system. The developed Personal health monitoring device (PHMD) functions satisfactorily and is ready for clinical trial. The mass production of this device will reduce overcrowding of patients at the healthcare centers as monitoring which is part of patient healthcare services can be done remotely and effectively.
