Abstract: A diffusing capacity predicting apparatus according to the present disclosure includes a memory including one or more instructions and a processor which executes the one or more instructions stored in the memory. In the memory, first information about a spirometry result of a user, second information which is clinical information, a first machine learning model, and a second machine learning model are recorded. The processor inputs the first information to the first machine learning model to extract a feature related to a lung disease and inputs the extracted feature and the second information to the second machine learning model to predict a diffusing capacity value of the user. Accordingly, the diffusing capacity may be more accurately predicted using the spirometer result and the artificial intelligence model, without using the diffusing capacity test method.
