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)
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 and how to...
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.
Pulmonary function tests (PFTs) are non-invasive diagnostic tests used to evaluate lung physiology, identify pulmonary pa-thology and monitor the progression of respiratory conditions. They are also used to assess the efficacy of medication and treatments, in both research and clinical settings.
Pulmonary function tests can provide important clinical information, yet they are vastly underused. They are designed to identify and quantify defects and abnormalities in the function of the respiratory system and answer questions such as the following: How badly impaired is the patient’s lung function? Is air-way obstruction present?
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 blood stream. The most common PFT’s are spirometry (spy-RAH-me-tree), difusion studies, and body plethysmography (ple-thiz-MA-gra-fee).
