INTEGRATION OF A WEARABLE INSTRUMENTATION SYSTEM FOR THE MEASUREMENT OF ELECTROPHYSIOLOGICAL VARIABLES IN THE DIAGNOSIS OF SLEEP APNEA.

Monitoring for the diagnosis of sleep apnea. One of the most frequent sleep disorders is sleep apnea, this disorder is caused by small breathing pauses during sleep that are repeated several times at bedtime. A wearable instrumentation system has been designed in charge of monitoring, storage and visualization of physiological signals, of which three signals were used (ECG, accelerometer and pulse oximeter). General objective Integrate a wearable system for the acquisition and monitoring of electrophysiological variables related to the diagnosis of sleep apnea. Specific objectives • Implement an electronic system for the acquisition of physiological signals. • Design algorithms for digital signal processing. • Design a visualization system for the user. Said system will be a user interface. • Validate the operation of the designed system. Scope: Development of a system for the acquisition of biomedical signals. •View signals from a desktop computer. • The processing of the signals will be visualized in a graphical interface. • The validation will be based on the parameters of each signal and the outputs of each sensor. Limitations • The size of the hardware may be limited by the cost of the elements that will be used. • The acquisition time of the sensors. Conclusions Mainly, the fulfillment of the specific objectives was achieved, of which, the implementation of a device for the acquisition of physiological signals was fulfilled. Also, with the help of Arduino’s own programming language, the objective of designing algorithms for digital signal processing was met. The data obtained by each sensor were displayed for further analysis.
