The forced expiratory volume in one second (FEV1) is the volume of air exhaled in the first second of the FVC maneuver. That means you will be required to know the normal ranges in order to select the correct answer. FVC is about 2 percent greater in patients who are standing compared with patients who are supine. 7.

Office spirometry for lung health assessment in adults: A consensus statement from the National Lung Health Education Program. Textbook of respiratory medicine. 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. Table 1. Normal spirometry results. The final step in interpreting spirometry is to determine if additional testing is needed to further define the abnormality detected by spirometry. Fulmer JD, 9.

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. 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.

Fauci AS, 0000027501 00000 n 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. 2004 Mar 1;69(5):1107-1115. Mayo Clin Proc. Kannel WB, 0000027558 00000 n Spirometry is a medical test that measures the volume of air an individual inhales or exhales as a function of time. Because it is dependent on FVC, the FEF25–75% is highly variable. 1999; 159:179–87. Pulmonary function tests: comparison of 95th percentile-based and conventional criteria of normality. 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.

This also applies to the FEV1/FVC ratio or Tiffeneau index: according to the new interpretation method a FEV1/FVC ratio of 71% can be too low for a young adult where a FEV1-ratio of 68% can be perfectly normal for an elderly person. / afp (See table below.)
