In 1994, a statement on the performance of lung function testing was issued by the Association for Respiratory Technology & Physiology (ARTP), and it has been updated in 2020. In this paper, we introduced the updated content, including general procedures, normal value ranges and interpretations of obstructive ventilation dysfunction, precautions of lung function tests, and paediatric lung function testing. We also compared the differences between the ARTP statement and the lung function guidelines issued by the Chinese Thoracic Society (CTS) and put forward some appropriate suggestions from the viewpoint of our current situation. We expected it to provide valuable references for the normative update and application of pulmonary function tests in China.
