Pulmonary Function Test Results Chart. How To Interpret A Pulmonary Function Test. Hyatt, Robert E. , M.D. Some, such as spirometry and pulse oximetry, are widely used in a variety of healthcare settings; others, such as those that measure diffusing capacity and static lung volumes, are performed in specialist pulmonary function laboratories. One of the first questions in interpreting pulmonary function testing is the definition of what is "normal". 2. Pulmonary Function Testing. Approaches to Interpreting Pulmonary Function Tests .

Despite the large amount of data gathered, many questions and interpretation problems still exist. One of the frequent reasons patients see their primary care physicians is for the symptom of dyspnea. If so, a restrictive ventilatory defect is likely and I next look at the lung volume section. 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. Scanlon, Paul D. , et al. If the ratio is above 75%, are the FVC and FEV1 low? Pulmonary function tests (PFTs) are a group of tests that measure how well your lungs work.

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. 1994, pgs 798-893. However the physician or other licensed health care professional (PLHCP) may require a pulmonary function test as part of the medical evaluation along with any follow-up exams he/she may deem necessary. At this time however, the preponderance of evidence and opinion is in favor of the LLN so the recommendation has to be for those interpreting pulmonary function tests to use the LLN for all reference values, including the FEV1/FVC ratio, unless there are clear and overwhelming reasons not to. A low Vital Capacity confirms a restrictive ventilatory defect.
