The 2022 ERS/ATS technical standard provides a modern framework for interpreting routine pulmonary function tests. It addresses how clinicians should assess spirometry, lung volumes and diffusing capacity rather than interpreting an isolated number in isolation. The document emphasizes use of appropriate reference equations, recognition of patterns and integration of multiple measurements with the clinical context. It also updates the approach to defining abnormality and supports standardized terminology for reporting lung-function results. The practical value is substantial because pulmonary function testing is often used to confirm or refine diagnoses, characterize severity and follow disease over time. An apparently abnormal FEV1/FVC ratio, restrictive-looking pattern or reduced DLCO should therefore trigger a structured interpretation rather than an automatic diagnostic label. The standard fits directly with the NAPCON PFT workshop and symposium, particularly the emphasis on lung volumes, DLCO and practical interpretation beyond FEV1/FVC. For HCPs, it reinforces a simple principle: reliable interpretation depends on technically sound testing, appropriate reference ranges and pattern recognition. This publication is especially useful as a foundation for multidisciplinary discussions involving pulmonology, radiology and other clinicians managing complex breathlessness.
