WebPrior to every spiroergometry test in both conditions, T1 and T2, participants performed a lung function test with the same measuring device in order to determine forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), peak expiratory flow (PEF), as well as maximal expiratory flow at 75% and 25% of vital capacity (MEF). WebIntroduction. Both percentages of predicted forced expiratory volume in 1 second (FEV 1) and peak expiratory flow rate (PEFR) are widely used to estimate the degree of pulmonary impairment in patients with COPD. 1–3 In general, FEV 1 measurements by spirometry are preferred as it is much more reproducible. 4 However, spirometry is not widely available, …
