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 کاملSpirometry reference values in the Brazilian population
The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT)....
