Pulmonary Function Tests. If so, a restrictive ventilatory defect is likely and I next look at the lung volume section. Therefore, attempts to interpret pulmonary function tests solely on the basis of predesignated numerical standards has so many pitfalls that it may easily supply gross misinterpretations. Describe the clinical indications for pulmonary function testing 2. While computers designed for interpretation of pulmonary function tests are not generally sophisticated enough to do better, pulmonary clinical physiologists can do better. vol.

One of the first questions in interpreting pulmonary function testing is the definition of what is "normal". To become competent at interpreting spirometry results, an understanding of lung volumes, the diseases and conditions that may affect lung function, and plenty of practice is required. Among the objective tests to quantify this symptom is the pulmonary function test, which includes several different studies: spirometry with flow-volume loop, lung volumes, and diffusing capacity of lung for carbon monoxide. In general, this is my approach to interpreting a pulmonary function test: First, I look at the FEV1/FVC ratio. 2016 Feb;37(2):100-10. doi: 10.1016/j.revmed.2015.10.356.
