PROBLEM TO BE SOLVED: To provide a respiratory resistance measuring device or the like capable of information processing to support judgment. A respiratory resistance measuring device is a respiratory resistance measuring device that processes additional data indicating a new measurement result based on data indicating a measurement result of a subject performed in the past, and has a normal respiratory function. A storage unit that stores the first data indicating the measurement result of the case and the second data indicating the measurement result when there is an abnormality, and the correlation between the additional data and the first data based on the first data and the second data. The control unit includes a control unit that determines at least one of the correlation between the additional data and the second data, and the second data includes NG data indicating the measurement result when the usage of the respiratory resistance measuring device is inappropriate. If it is determined that the additional data corresponds to the second data, further determines whether it corresponds to the NG data.
