The Truth Experts ATS Recommended Use Of Lower

The truth experts ATS Recommended use of lower values of specifications instead of 80 % The predicted level of a threshold which, usually, defines not Correct or wrong results of tests. Reduction FVC at in absence Reduced relation FEV1 to FVC assumes more often Infringements in lungs. Not proportional reduction of volumes of an exhalation At can result and in reduction FVC. The reasons of the such Reductions of volumes consider the fatness, inadequate breath, , Pregnancy, pleural , pleura tumours, , , pulmonary , muscular diseases, weakness or Diaphragm paralysis, occupational diseases of lungs, consequences Lung resection, warm insufficiency and serious obstruction Lungs. And-or FEV1 it is possible for degree of reduction of volumes FVC To distribute according to the following scheme: As moderated - 70-79 % From the settlement; average - 60-69 %; serious - 50-59 %; very much The serious; - 35-49 % and critical - less than 35 % from settlement.
