A Novel Approach to the Respiratory Disease Follow-up Based on Plethhysmography Signal Parameters

Aim: The aim of this paper is to present a novel approach for the monitoring respiratory diseases based on combined study heart rate, rate and Pulse Oximetry (SpO2). Introduction: Since start COVID-19 pandemic, have increased its worldwide prevalence dramatically. Added impact pandemic already existing situation growing such as bronchial asthma Chronic Obstructive Pulmonary Disease (COPD). On other hand, it known that cardiovascular system overloaded when there are insufficiencies condition can cause severe damage health. Pulmonology Cardiology independent medical specialties deal with these often do not cooperate each strongly, so proposal presented combines variables health problem. Methods: A prototype was developed STM32L073CZTx processor controlling E305654 pulse oximetry module, which demand delivers SpO2, photo plethysmography signal samples values. vector computed, every thirty minutes, combine obtained from Plethysmography Signal (PPG), mean value SpO2 rate. module represents systems performance. Results: Twenty healthy volunteers, twenty people COPD five subjects suffering asthma, during periods without crisis, were studied. dispersion within group patient significant, but notable difference be observed between volunteers "normal region" set clearly defined borders. Conclusion: proposed solution seems promising evaluating function even compensated by cardiac response, making easier identify who may appear normal or healthy.
