Office spirometry for lung health assessment in adults: A consensus statement from the National Lung Health Education Program. People living with chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, emphysema and other types of chronic lung diseases have had a spirometry test. Typically, doctors use spirometry to help them better under the severity of your chronic lung disease symptoms and how they affect your life. Address correspondence to Timothy J.

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.

Powell CA, The significance of the FEV1/FVC ratio is twofold. (See table below.) Absolute FEV 1 /FVC ratio. — Determine zero flow level (if required for the spirometer) ... Normal spirometry Obstruction Responsive expiratory airflow limitation Possible restriction Obstruction, (DLCO = diffusing capacity of lung for carbon monoxide; VA = alveolar volume. Kiley JP, Together, the four lung volumes equal the total lung capacity (TLC). 20. Philadelphia: Saunders, 2000:783. In: Murray JF, Nadel JA, eds. 0000026916 00000 n 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. Pulmonary function testing: sources of error in measurement and interpretation. Normal values in healthy males aged 20-60 range from 4.5 to 3.5 liters, and normal values for females aged 20-60 range from 3.25 to 2.5 liters. If the FVC and the FEV1 are within 80% of the reference value, the results are considered normal. J Resp Dis 1999;20:812.
