Design of an electronic device for the measurement of respiratory signals

Respiratory problems while sleeping cause several health effects, thus it becomes important to monitor respiratory signals to search the causes or moments when said health effects occur. This paper presents the design of an electronic system that first measures, then is instrumented and finally captures signals related to breathing: nasal flow and chest and abdomen respiratory effort. The designed device achieves the visualization of the previously mentioned signals through the Matlab software for its subsequent analysis, ensuring that the system can detect apnea and hypopnea events based solely on the respiratory signals.
