Review age, gender, smoking status, BMI, indication, flow-volume curves. Quality control. Three acceptable maneuvers with repeatable values: Two highest values of FVC and FEV1 should be within 150mL (100mL if FVC ≤ 1L)
5 Ιουν 2012 · In this article we will provide an overview of basic pulmonary function tests and an algo-rithm for using and interpreting them, and then we use three cases to explain how to use these tests to identify the pattern of respirato-ry dysfunction, then make the diagnosis.
Describe the clinical indications for pulmonary function testing. Understand the physiology of the core pulmonary function tests: spirometry, lung volumes and DLCO. Apply an organized approach to interpreting pulmonary function tests. Identify obstructive, restrictive, mixed obstructive-restrictive and pulmonary vascular patterns of ...
15 Μαΐ 2024 · This pulmonary test analyzer will help you understand your FVC, FEV1, VC, and other pulmonary test results. Select a test and enter your lab value to learn more.
Interpreting results. Best of 3 consistent readings (FEV1 & FVC) Borderline normal results - repeat in few months to confirm diagnosis (especially > 75 years) Abnormality detected if any of following recorded: FEV1 <80% predicted normal. FVC <80% predicted normal.
27 Φεβ 2017 · Lung Volumes and Restriction •The test is most reliably interpreted as showing restrictive abnormality on the basis of total lung capacity. •The presence of Restrictive Physiology is based on TLC < LLN pred •The severity of the abnormality is based on •FEV1 •TLC (much less validated) –use if there is no spirometry
If FVC < LLN (or < 80%) predicted, consider hyperinflation/gas trapping. If post-BD FVC remains < LLN (or < 80%) predicted, consider combined obstructive and restrictive defect and full PFT. Note: Recommended reference equations: GLI, CHMS, and NHANES III. 2018 Ontario Lung Association.
