Diseño e implementación de un sistema no invasivo de monitoreo de la presión arterial y de la frecuencia cardiaca combinadas: sistema electrónico de control para el tensiómetro.

Abstract

Ambulatory pressure monitoring has acquired great importance in medical practice, becoming the first method to detect arterial hypertension and is an efficient mechanism for analyzing certain pharmacological treatments. The estimation of systolic and diastolic blood pressure with the oscillometry method has allowed the development of non-invasive digital devices for ambulatory monitoring. Under this context, in the present work, using the oscillometric method, the necessary software for the automation of the control system of a tensiometer is implemented, the timing of the automation is programmed that obeys parameters collected from the user using an interface Simple and useful graph. The devices used for ambulatory monitoring are characterized by accompanying the user in their daily activities, for this reason the prototype uses WIFI communication and using the HTTP and Web Socket protocols for sending and receiving information, the prototype becomes a mobile device, Since data processing and storage are not performed on the device, it becomes essential to implement a REST API, used as a means of exchanging information between various programs and the database, making use of it to perform a data pre-processing in Matlab to estimate systolic and diastolic pressure and heart rate.
