Obstructive lung disease and low lung function in adults in the United States: data from the National Health and Nutrition Examination Survey, 1988–1994. Spirometry begins with a full inhalation, followed by a forced expiration that rapidly empties the lungs. When the FVC and FEV1 are decreased, the distinction between an obstructive and restrictive ventilatory pattern depends on the absolute FEV1/FVC ratio. 3d ed. Reprinted with permission from Gold WM.

Before PFT results can be reliably interpreted, three factors must be confirmed: (1) the volume-time curve reaches a plateau, and expiration lasts at least six seconds (Figure 2); (2) results of the two best efforts on the PFT are within 0.2 L of each other (Figure 3); and (3) the flow-volume loops are free of artifacts and abnormalities.5 If the patient's efforts yield flattened flow-volume loops, submaximal effort is most likely; however, central or upper airway obstruction should be considered.

The role of pulmonary function testing in pulmonary fibrosis. Palma WR Jr. Chronic obstructive pulmonary disease (COPD) is the most common respiratory disease and the fourth leading cause of death in the United States.1 Despite preventive efforts, the number of new patients with COPD has doubled in the past decade, and this trend is likely to continue.2,3 Evidence indicates that a patient's history and physical examination are inadequate for diagnosing mild and moderate obstructive ventilatory impairments.4 Although a complete pulmonary function test provides the most accurate objective assessment of lung impairment, spirometry is the preferred test for the diagnosis of COPD because it can obtain adequate information in a cost-effective manner. The clinical context of the test is important because parameters in patients with mild disease can overlap with values in healthy persons.26 Normal spirometry values may vary, and interpretation of results relies on the parameters used. :1145–9, 1231–5 of Normality ( LLN ) GLI spirometry normal values no!
