Abstract
The present invention relates to the technical field of pulmonary function testing, and in particular to a pulmonary ventilation function testing device, method and system. The present invention quantifies the tension of a subject through waveform changes of an electrocardiogram (ECG) curve and amplitude fluctuations of an arm electromyography (EMG) curve to determine an initial tension level, and corrects the initial tension level based on the characteristic that the tension expressions presented by the ECG curve and the arm electromyography curve when the subject is nervous are consistent, thereby determining a corrected tension level that more accurately represents the tension level; and then corrects the initial pulmonary ventilation volume timing curve based on the corrected tension level, thereby solving the problem of inaccurate measurement of the pulmonary ventilation function of a subject by directly measuring the pulmonary ventilation volume timing curve of the subject in existing pulmonary ventilation tests, thereby improving the accuracy of pulmonary ventilation function testing based on the corrected pulmonary ventilation volume timing curve.
