1. Increased public awareness of COPD led to the formation of the National Lung Health Education Program (NLHEP) as part of a national strategy to combat chronic lung disease.9 The World Health Organization and the U.S. National Heart, Lung, and Blood Institute recently published the Global Initiative for Chronic Obstructive Lung Disease to increase awareness of the global burden of COPD and to provide comprehensive treatment guidelines aimed at decreasing COPD-related morbidity and mortality.10. / Vol. afpserv@aafp.org for copyright questions and/or permission requests.

These NHANES 1999 regressions are recommended for ethnically appropriate individuals by the ATS/ERS Task Force:2005 ‘Standardization of Lung Function Testing’.

Clinical spirometry in normal men. In: Murray JF, Nadel JA, eds. Textbook of respiratory medicine. A spirometermeasures the speed that lungs change in volume during forced breathing exercises beginning with a full inhalation, you rapidly empty your lungs of air and continue until max exhalation volume. However, the FEV1/FEV6 ratio provides accurate surrogate measure for the FEV1/FVC ratio.12 The reported FEV1 and FEV6 values should be rounded to the nearest 0.1 L and the percent predicted and the FEV1/FEV6 ratio to the nearest integer.13.

Spirometry is designed to identify and quantify functional abnormalities of the respiratory system. The Framingham study identified a low forced vital capacity (FVC) as a risk factor for premature death.6 The Third National Health and Nutritional Examination Survey and the multicenter Lung Health Study showed potential benefits for patients with early identification, intervention, and treatment of COPD.7,8 The Lung Health Study was the first study to show that early identification and intervention in smokers could affect the natural history of COPD.7 These surveys also showed that simple spirometry could detect mild airflow obstruction, even in asymptomatic patients. The forced expiratory volume in one second (FEV1) is the volume of air exhaled in the first second of the FVC maneuver. Normal value (95 percent confidence interval) FEV 1.

It should be used with caution in patients with advanced COPD because of its inability to detect very low volumes or flows. Different spirographic and flow volume curves are shown in Figure 2.11 It is important to understand that the amount exhaled during the first second is a constant fraction of the FVC, regardless of lung size. The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65). Gin K. When the FVC and FEV1 are decreased, the distinction between an obstructive and restrictive ventilatory pattern depends on the absolute FEV1/FVC ratio. Philadelphia: Saunders, 2000:781–871. FEV 1. Lopez AD. The primary way in which spirometry results are assessed is by comparing them to normal or reference values. The test is positive if the FEV1 increases by at least 12 percent and the FVC increases by at least 200 mL. Some portable office spirometers replace the FVC with the FEV6 for greater patient and technician ease. Normal spirometric flow diagram.

The NLHEP recommends that primary care physicians perform spirometry in patients 45 years of age or older who are current or former smokers; in patients who have a prolonged or progressive cough or sputum production; or in patients who have a history of exposure to lung irritants.9 Other indications for spirometry are to determine the strength and function of the chest, follow disease progression,15,16 assess response to treatment,17,18 and obtain baseline measurements before prescribing drugs that are potentially toxic to the lungs, such as amiodarone (Cordarone) and bleomycin (Blenoxane).19 Spirometry also is helpful in preoperative risk assessment for many surgeries20-23 and often is used in workers' compensation and disability claims to assess occupational exposure to inhalation hazards.24  Tables 3 and 4 list indications and contraindications for spirometry.
