References values for forced spirometry
Selected sets of reference values for forced spirometry derived from nonsmoking, white subjects [1] show marked differences among studies [2–6] in both predicted forced vital capacity (FVC) (up to 640 mL) and predicted forced expiratory volume during the first second (FEV1) (up to 310 mL). The magnitude of the differences among reference values gives rise to potential concerns for the clinical ...
متن کاملUse of the forced-oscillation technique to estimate spirometry values
PURPOSE Spirometry is sometimes difficult to perform in elderly patients and in those with severe respiratory distress. The forced-oscillation technique (FOT) is a simple and noninvasive method of measuring respiratory impedance. The aim of this study was to determine if FOT data reflect spirometric indices. PATIENTS AND METHODS Patients underwent both FOT and spirometry procedures prior to i...
متن کاملForced spirometry reference values for Norwegian adults: the Bronchial Obstruction in Nord-Trøndelag Study.
The purpose of this study was to develop new prediction equations for flow/volume spirometry parameters in asymptomatic, never-smoking adults in Norway, and to assess any differences of these parameters when applying the new and most commonly used equation sets. Flow/volume spirometry was measured according to the American Thoracic Society criteria in 2,792 subjects aged > or = 20 yrs, randomly...
متن کاملNew reference values for forced spirometry in white adults in Brazil.
OBJECTIVE To describe spirometric reference equations for healthy Brazilian adults who have never smoked and to compare the predicted values with those derived in 1992. METHODS Reference equations for spirometry were derived in 270 men and 373 women living in eight cities in Brazil. Ages ranged from 20 to 85 years in women and from 26 to 86 years in men. Spirometry examinations followed the r...
متن کاملReference values for spirometry in preschool children.
OBJECTIVES Reference values for lung function tests differ in samples from different countries, including values for preschoolers. The main objective of this study was to derive reference values in this population. METHODS A prospective study was conducted through a questionnaire applied to 425 preschool children aged 3 to 6 years, from schools and day-care centers in a metropolitan city in B...
