RSV = respiratory syncytial virus; tPTEF/ tE = exhaled time to reach peak expiratory flow as a fraction of total expiratory time; VmaxFRC = maximal flow at functional residual capacity produced by forced expiration as a result of a rapid chest compression; VPTEF/ VE = tidal volume exhaled at peak tidal expiratory flow as a fraction of total tidal volume.
Thus, maximal total costs and maximal total health effects were smaller.
A maximum of 8 maximal expiratory flow volume (MEFV) curves are performed, until three technically satisfactory measurements are achieved (ATS/ETS criteria).
Abbreviations: FVC Forced vital capacity, FEV1 Forced expiratory volume in 1 second, MEF Maximal mid-expiratory flow, TLC Total lung capacity, DLCO Diffusing lung capacity.
The following parameters were measured/calculated: peak expiratory flow (PEF); forced vital capacity (FVC, L); 1st second forced expiratory volume (FEV1, L); maximal mid expiratory flow (MMEF, L/s) or forced expiratory flow when x% of FVC has been exhaled (MEF x, L/s); FEV1/FVC ratio (absolute value); total lung capacity (TLC, L); residual volume (RV, L); and thoracic gas volume (TGV, L).
Gr.: group, FEV1: forced expiratory volume in one second; FVC: forced vital capacity; PEF: peak expiratory flow; MMEF: maximal mid expiratory flow; MEF75, MEF50 and MEF25: maximal expiratory flow at 75%, 50%, and 25% of the FVC respectively.
We analyzed the following volume and flow parameters: forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), peak expiratory flow (PEF) and maximal mean expiratory flow (MMEF).
No significant difference was observed in % predicted values of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC, peak expiratory flow (PEF) and maximal mid expiratory volume FEF25-755) betheen the photocopier operators and control subjects.
The highest level for forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), maximal mid expiratory flow (MMEF), maximal expiratory flow at 75%, 50%and25%5% of the FVC (MEF75, MEF50 and MEF25 respectively) were taken independently from the three curves.
In patients with normal lungs, the spatial distribution of the maximal signal expiratory vibration response image was lower than the maximal signal during inspiration.
