Breathing parameter extraction method and system

The invention discloses a breathing parameter extraction method, system and device and a computer readable storage medium. The method comprises the steps that single-mouth breathing waveform data of a to-be-tested person is obtained; the breathing waveform data of the to-be-tested person comprises single-mouth breathing waveform data segmented based on a flow velocity waveform; analyzing and processing the single-mouth breathing waveform data of the to-be-tested person to obtain breathing parameters of the single-mouth breathing waveform data segmented based on the flow velocity waveform; and outputting the breathing parameters. According to the invention, automatic segmentation of respiration can be realized based on the real-time or offline flow velocity waveform, and the accuracy of respiration segmentation is effectively ensured; meanwhile, monitoring parameters are obtained based on the single-mouth breathing waveform, and an auxiliary treatment decision is made for the patient. 本发明公开了一种呼吸参数提取方法、系统、设备和计算
