Cardiac interference identification method for medical ventilation equipment and medical ventilation equipment

A cardiogenic interference identification method (100) for a medical ventilation device and a medical ventilation device (600), the method comprising: acquiring a first signal and a second signal obtained by monitoring a ventilation subject by the medical ventilation device (600), the first signal comprising a flow rate signal; identifying fluctuation of the flow velocity signal according to the flow velocity signal and the second signal; and acquiring fluctuation characteristics of the fluctuation, and identifying the cardiac interference in the fluctuation based on the fluctuation characteristics of the fluctuation. The method identifies cardiac interference based on signals acquired by the medical ventilation device (600) itself, does not require physiological signals of an external device, and has obvious clinical use value. 一种用于医疗通气设备的心源性干扰识别方法(100)和医疗通气设备(600)，该方法包括：获取医疗通气设备(600)对通气对象进行监测所得到的第一信号和第二信号，第一信号包括流速信号；根据流速信号和第二信号识别流速信号的波动；获取波动的波动特征，并基于波动的波动特征识别波动中的心源性干扰。该方法基于医疗通气设备(600)自身采集的信号识别心源性干扰，无需外部设备的生
