Abstract
This section, mainly drafted by R. Pellegrino, G. Viegi, P. Enright, V. Brusasco and R. Crapo, generated rather strong controversy, but only in a couple of areas. It emphasises the importance of selecting appropriate reference values and lower limits of the normal range, and provides a good listing of available reference studies with suggestions for dealing with ethnicity. Nevertheless, the committee realised that no single set of reference values can be recommended and more work will be necessary in this area. A detailed interpretative algorithm is presented, outlying the position of each test for a state-of-the-art diagnostic procedure in large hospital-based laboratories. Its use is not intended as mandatory and simpler assessments of pulmonary function are acceptable in different settings, keeping in mind the limitations that are inherent to simplicity. The assessment of reversibility of bronchoconstriction is covered in more detail than in previous documents, with reminders that a number of chronic obstructive pulmonary disease patients are more likely to respond with improvements of lung volumes than forced expiratory volume in one second. As for any recommended standard, this one is not perfect, but reflects the current knowledge in the field. Therefore, it should be used as a guide for good clinical practice until changes are made based on new scientific evidence. A future goal would be the creation of standard pulmonary function reports, which present the relevant data in a format that enables an ''easy interpretation and digestion of the information''.File | Dimensione | Formato | |
