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.
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 cze 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.
Physicians can use the following stepwise approach to not only interpret PFTs from their office or a pulmonary function labora-tory, but also determine when to order fur-ther testing...
A lung function test involves you breathing into different pieces of equipment in order to test how well your lungs are working. There are several different lung function tests that your doctor may refer you for, these include: • spirometry. • bronchodilator reversibility test. • gas transfer measurement.
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). Expiratory Reserve Volume (ERV): The volume of air that is expelled from the lung during a maximal forced expiration that
Pulmonary function tests (PFT’s) are breathing tests to find out how well you move air in and out of your lungs and how well oxygen enters your body. The most common PFT’s are spirometry (spy-RAH-me-tree), diffusion studies and body plethysmography (ple-thiz-MA-gra-fee).
