The invention provides a method, a device, a breathing machine and a storage medium for detecting apnea types. The method includes exerting first oscillation pressure waves with set amplitude values Aand set frequencies f on ventilation pipelines by fans under the control when apnea occurs; carrying out filter processing on first pressures P (t) of the ventilation pipelines to obtain second oscillation pressure waves P '(t) and acquiring amplitude values B of the second oscillation pressure waves; computing leakage resistance R of patient mask ends of breathing masks; computing airway resistance R of patients; determining the apnea types according to the airway resistance R and preset airway resistance thresholds R. The ventilation pipelines are ventilation pipelinesbetween fan gas outlets of the fans and the breathing masks. The method, the device, the breathing machine and the storage medium have the advantages that the airway resistance of the patients in apnea states can be measured by the aid of the meth
