the bronchoconstriction was evaluated with specific lung conductance ( sgl ) , maximum partial ( initiated from end-inspiratory lung volume ) expiratory flows assessed at 40 % vital capacity breathing air ( vmax40p air ) , and a he-o2 mixture ( vmax40p he ) , and with maximum complete flows breathing he-o2 [ forced expiratory volume at 1 s ( fev1 ) , vmax50c he ] .
