* The Smoothness Of An Inclination Of A

* The smoothness of an inclination of a curve in any is marked Volume of an exhalation of a lung that reflects reduction of a stream exhaled Air. * Duration of the forced exhalation always ; changes are visible at comparison with norm and are reduced in FEV1, FEV3, the relation FEV1-to-FVC, FEV3-to-FVC, and FEF (25-75 %). * There is an insignificant decrease in streams of an air line: FVC-> = 81 % due, but FEF (25-75 %) <65 %. FEV1 Interpretation > 80 % from the due Norm 66-80 % from the due Small obstruction 50-65 % from the due Obstruction of average degree <50 % from the due Strong obstruction Relation FEV1 to FVC > = 70 % from the due Norm 61 - 69 % from due Small obstruction 45 - 60 % from due Obstruction of average degree <45 % from the due Strong obstruction FEF (25-75 %) > = 66 % from the due Norm 50 - 65 % from due Small obstruction 35 - 49 % from due Obstruction of average degree <35 % from the due Strong obstruction Restriktivnye processes in lungs are characterised by following changes: * Configurations volume-time should be considered in dynamics.
