  1. Values in parentheses correspond to one standard deviation. The parameters VT = tidal volume; Tbc = time of a breath cycle; VE = minute volume ventilation rate are values recorded during the deposition measurements. VDaw corresponds to anatomical airway dead space and R5 and R20 to the resistance of the respiratory system measured with impulse oscillometry at 5 Hz and 20 Hz, respectively
