His TLC is elevated and his diffusing capacity is very low. The results may indicate both respiratory and nonrespiratory disorders, including helping in the diagnosis of cardiac or neuromuscular diseases. Like the six minute walk test, PFTs are only useful if they are performed the same way each time with maximal effort. His FEV1/FVC ratio is < 70% which indicates obstruction. If so, a restrictive ventilatory defect is likely and I next look at the lung volume section. Chest Med. If you continue browsing the site, you agree to the use of cookies on this website.

[Interpretation and Use of Routine Pulmonary Function Tests: Spirometry, Static Lung Volumes, Lung Diffusion, Arterial Blood Gas, Methacholine Challenge Test and 6-minute Walk Test] Rev Med Interne. Pulmonary function tests (PFTs) are a group of tests that measure how well your lungs work. Before interpreting any of the pulmonary function data, it is important to ensure that you are looking at a valid test. utilizes the many references available on interpretation oflung function and provides a teaching/reference tool for reportwriting of lung function results routinely performed in clinicalpractice. Interpretation of Pulmonary Function Tests. Pulmonary Function Tests. Clin. It is a reliable method of differentiating between obstructive airways disorders (e.g. Textbook of Respiratory Medicine, Murray JF & Nadel JA eds. Pulmonary Function Interpretation For Dummies . In general, this is my approach to interpreting a pulmonary function test: First, I look at the FEV1/FVC ratio. I. Problem/Condition Indication for Testing. FEV1/FVC ratio results in a significant number of false-positive results in males aged .40 yrs and females .50 yrs [12], as well as in a risk of overdiagnosis of chronic obstructive pulmonary diseases (COPD) in asymptomatic elderly never-smokers [19]. They’re noninvasive, which means that the doctor doesn’t cut you or put any tools inside your body. Despite the large amount of data gathered, many questions and interpretation problems still exist.
