Resumen

This paper presents the implementation of a real-time remote biosignal monitoring system based on Internet of Things technology. The number of people requiring medical attention is increasing, and with the passage of the pandemic, it became known the deficiencies of the state medical sector, especially in non-urban areas of the department of Arequipa. Forcing people with limited resources to travel to hospitals with greater capacity which is a high risk for critical patients. One of the causes of this situation is the low budget that is managed in rural hospital centers, which is why we have developed 3 low-cost sensors that can detect heart rate signals, body temperature and blood pressure, all in real-time through a dashboard both a web and mobile application. The IoT interface was developed on the BLINK platform. The results of these low cost sensors were validated against other commercial sensors generally used in hospitals, verifying their reproducibility and accuracy by having a coefficient of variation of less than 5%. The tests were performed in the emergency area of the Honorio Delgado Espinoza Regional Hospital in Arequipa.
