摘要:
The present invention relates to a breathing waveform recognition method, which includes: (a) detecting a breathing flow in a breathing cycle (b) measuring an amplitude of the breathing flow and the duration of the breathing cycle (c) using a plurality of sampling points to determine an inhale waveform and an exhale waveform according to the amplitude and the duration (d) normalizing the amplitude and the duration for one of the inhale waveform and the exhale waveform to establish a normalized waveform and (e) accumulating the differences between the normalized waveform and a reference waveform to calculate a flow coefficient, which may determine if the normalized waveform is recognized as a normal breathing state or an abnormal breathing state. This invention utilizes a curve (or a weighted curve, standard waveform) for fitting the inhale waveform or the exhale waveform to calculate the difference, and recognizes the normal breathing state or the abnormal breathing state by accumulation of the differences. This invention further provides a breathing waveform recognition system.本發明係一種呼吸波形辨識方法,係包含(a)在一呼吸週期偵測一呼吸氣流;(b)測量該呼吸氣流的一振幅與測量該呼吸週期的一時間;(c)複數取樣點依照該振幅與該時間決定一吸氣波形與一呼氣波形;(d)正規化該吸氣波形與該呼氣波形之其中一者的該振幅與該時間,以建立一正規化波形;以及(e)累加一參考波形與該正規化波形之間的差值,以計算出一流量係數,該流量係數決定該正規化波形能被識別為一正常呼吸狀態與一非正常呼吸狀態。本發明利用一曲線(或加權曲線、標準波形)擬合該吸氣波形或該呼氣波形,以計算出差值,並藉由累積該差值以辨別出該正常呼吸狀態與該非正常呼吸狀態。本發明另提供一呼吸波形辨識系統。S11-S15‧‧‧方法步驟
