After introducing this new calculated correction factor (10.58% for PEF and 4.15% for FEV1), excellent agreement between the 2 devices was found, both for PEF (ICC=0.9652; 95% CI, 0.9336-0.9819) and for FEV1 (ICC=0.9876; 95% CI, 0.9761-0.9936).

More Definitions of FEV1

FEV1 means the forced expiratory volume in 1 second as measured by a spirometric test performed as described in the most cur- rent American Thoracic Society Statement on Standardization of Spiro metry, and using equipment, methods of calibration, and techniques that meet American Thoracic Society (ATS) criteria including reprodu- cibility. The measurement used must be taken from a spirogram which is technically acceptable and represents the patient's best effort. The measurement is to be expressed as both an absolute value and as a per- centage of the predicted value. The predicted values are those listed in the most current edition of the American Medical Association (AMA) Guidelines for rating permanent respiratory impairment.

FEV1 means forced expiratory volume in the first second, which is the maximal volume of air expelled in one second during performance of simple spirometric tests. "FVC" means forced vital capacity that is maximal volume of air expired with maximum effort from a position of full inspiration. "Spirometry" means the measurement of volume of air inhaled or exhaled by the lung. "ILO scale" means the system for the classification of chest x-rays set forth in the International Labour Office's Guidelines for the Use of ILO International Classification of Radiographs of Pneumoconioses (1980) as amended. "Certified B-reader" means an individual qualified as a "final" or "B-reader" as defined in 42 C.F.R. § 37.51(b), as amended. (R.C. 2307.91(I), (M), (N), (O), and (AA).)
