摘要:
A respiratory waveform recognition method comprises: (a) detecting a respiratory airflow in a respiratory cycle; (b) measuring an amplitude of the respiratory airflow and a duration of the respiratory cycle; (c) using a plurality of sampling points to determine an inspiration waveform and an expiration waveform according to the amplitude and the duration; (d) normalizing the amplitude and the duration of one of the inspiration waveform and the expiration waveform, so as to establish a normalized waveform; and (e) accumulating the differences between the normalized waveform and a reference waveform to calculate a flow index useful for the identification of a normal respiration state and an abnormal respiration state. A curve, such as a weighted curve or a standard waveform, is used for fitting of the inspiration waveform or the expiration waveform to calculate the differences, and the differences are accumulated to identify the normal respiration state and the abnormal respiration state. Also provided is a respiratory waveform recognition system.
