This open-access website aims at promoting the understanding of respiratory physiology and pathophysiology, with emphasis on the measurement and interpretation of spirometric test results.
SpirXpert was created and managed for many years by Professor Philip H Quanjer, Emeritus Professor of Physiology in Leiden, The Netherlands. Professor Quanjer was a co-founder of the European Respiratory Society and European Respiratory Journal. He passed away on July 26th 2017 at the age of 80 years. Before his death, Professor Quanjer passed on SpirXpert to the ERS, who has taken over hosting the site and will continue to maintain it as a free and open-access resource for future generations.

The final evaluation of spirometric data, and any decisions about diagnosis, treatment and other interventions in patients remain the sole responsibility of the physician in charge of the patient, who should come to a conclusion on the basis of information from various sources, of which spirometric data form a part.
It is recommended that you acquire basic background knowledge before embarking on performing spirometry or interpreting test results. Concise and essential information is available in the following chapters:
A good working knowledge of the pathophysiology of flow limitation is indispensible for optimally performing spirometry and interpreting test results. Recommended reading:
