Normal spirometry values in healthy elderly: the Rotterdam Study. Eur J Epidemiol. 2013; 28(4):329-34.Loth DW, Ittermann T, Lahousse L, Hofman A, Leufkens HG, Brusselle GG, et al. Normal spirometry values in healthy elderly: the Rotterdam study. Eur J Epidemiol. 2013;28:329-34....
(Method of Least Squares)a set of equations of the first degree equal in number to the number of unknown quantities, and derived from the observations by a specified process. The solution of the normal equations gives the most probable values of the unknown quantities. ...
The predictive values for FeNO (usually at cut-off points >25 ppb) were shown to be sufficiently robust to be used in the context of diagnosis – more than for conventional measurements such as peak flow and spirometry, and similar to those associated with bronchial challenge tests.2 In patie...
Spirometry was performed as recommended by the American Thoracic Society, using Vmax22 (SensorMedics, Yorba Linda, CA, USA). Absolute Values of FVC and FEV1 were obtained and the percentage of predicted values (% pred) for FEV1 and FVC were calculated from the following equations obtained in a...
Methods: Thirty three finnish MUL patients (median age 20 years) were investigated with several lung function tests: spirometry with bronchodilatation test, single-breath diffusing capacity for carbon monoxide, single-breath lung volume measurements with helium dilution, and thoracic gas volume, airway ...
Methods : In each of 6 ethnic/gender, never-smoking NHANES-3 groups, arranged sequentially by age from 20.0 to 79.9 years, the values of FEV 1 /FEV 6 , FEV 1 /FVC, FEV 3 /FEV 6 , and FEV 3 /FVC were placed in groups of 40 so that the actual lowest second (5%) ratios could...

Methods: 182 adolescents with a mean age of 15卤2 (age range from 12 to 18 years old) were assessed: 98 boys (BMI: 20卤3.15 Kg/m2) and 84 girls (BMI: 19卤4 Kg/m2). Spirometry was performed prior to the assessment of respiratory muscle strength. MIP and MEP were measured with a...
