Method and apparatus for monitoring respiration using photoplethysmograph sensor

摘要

Embodiments of the present specification provide a computer implementation method and system for respiratory monitoring.Some embodiments determine the peak and trough of the PPG signal stream in a given epoch, and peak amplitudes within a predetermined epoch To determine the significant minima of the significant maxima and trough amplitudes and to determine the number of significant maxima, the number of significant minima, or both of them in a predetermined epoch to determine the number of respiratory efforts in a given epoch TapeA method of displaying the number of breathing efforts in a given epoch on a computer monitor, including the time between peaks or trough, corresponds to the heart rate of each individual, and the number of significant peaks of peak amplitudes for each ejection Corresponding to the onset of the respiratory effort of the body, each significant minimum value of the trough amplitude corresponds to the onset of the respiratory effort of the individual for inhalation.Diagram
