Application of remote monitoring of biosignals and geolocation with a wearable for patients with sequelae of the coronavirus

Abstract

Several patients who have overcome coronavirus disease (COVID-19) have been left with cardiovascular and pulmonary sequelae and most medical centers lack a remote monitoring system for each patient that notifies them of any complications during rehabilitation. The objective of this research was to implement a wearable that monitors the patient’s health and alerts in case of detecting any anomaly. For this reason, a wearable was developed that displays the patient’s heart rate, oxygen saturation (SpO2) level and body temperature on the light emitting diode (LCD) and the application mobile, sending an alert and geolocation message if anomalies are detected in vital signs. The standard deviation of heart rate, temperature and SpO2 was obtained, which was 1.4930, 0.1558, and 0.4364 in the rest stage, respectively, and 6.3442, 0.2365, and 0.9186 in the physical activity stage respectively with a maximum duration of 42 hours and 52 minutes of battery, managing to send alert messages and store the information in the cloud, which allows to conclude that the wearable can facilitate the management of the database and the location of the patient, that the measurement error increases with physical activity, and that battery life varies with the number of biosignal readings per hour.
