abstractsLung diffusing capacity tests can assess the gas exchange function of the alveolar capillary membrane.With the widespread implementation of pulmonary function tests in children and the continuous improvement of testing techniques, the number of diffusing capacity tests in children has been increasing.However, there are currently no guidelines or consensuses available.This consensus provides a detailed explanation of the principles, methods, indications, contraindications, result interpretation, and clinical application of lung diffusing capacity tests in children, in order to help standardize the operation and rational application of these tests in clinical practice.
