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)
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 ...
3 Interpretation Of Pulmonary Functions Tests A Practical Guide Published at www.greenrabbit.se Restrictive Lung Diseases: These conditions, including interstitial lung diseases, pulmonary fibrosis, and neuromuscular disorders, limit lung expansion, restricting the amount of air the lungs can hold. PFTs reveal a reduced FVC, often with a
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.
LUNG VOLUMES & CAPACITIES: Tidal Volume (VT):The volume of air entering the nose or mouth per breath (500 ml). Residual Volume (RV): The volume of air left in the lungs after a maximal forced expiration (1.5L).
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.
Every doctor involved in acute medicine deals with blood gas or lung func-tion data. Although a wealth of information lies therein, much of the content may be lost on the non-specialist. Frequently the information necessary for interpretation of basic data is buried deep in heavy specialist texts. #is book
