APPARATUS FOR DETERMINING RESPIRATORY CONDITION |
摘要 |
An apparatus for determining a respiratory condition, the apparatus includes: a signal acquirer which is configured to acquire a signal waveform corresponding to a respiratory flow of a subject; a differential calculator which is configured to acquire a differential waveform which is obtained by performing differentiation of the signal waveform; and a first determiner which is configured to determine that inspiratory flow to limitation occurs in the subject, when the differential waveform satisfies a predetermined condition in a portion of the signal waveform, which corresponds to inspiration of the subject. |
