An increased FEV1/FVC ratio is also possible, and this is usually associated with a restrictive lung disease pattern.

Performance of a spirometry and important measures The current guideline for spirometry (CrieØ et al., 2015) describes in detail how spirometry is to The Normal Spirometry Values are: • Tidal volume is 400 to 500 ml (10 mI/kg). • Inspiratory reserve volume is is 2,400 to 2,600 ml. • Inspiratory capacity is inspiratory reserve volume + tidal volume i.e 2,500 (IRV) + 500 (TV) = 3,000 ml • Expiratory reserve volume is 1,200to 1,500 ml.

This tells you the percentage of your lung’s air space that you can exhale in one second. Normal results are 70% or more for adults under 65. FVC/FEV-1 ratios below normal help your doctor rate the severity of your lung condition: Mild lung condition: 60% Low FEV1/FVC with normal FEV1 Sometimes the ratio of FEV1 to FVC is below the lower limit of normal (-1.645 SR), with the FEV1 being in the normal range but the subject's FVC being much greater than predicted. There is some uncertainty about the clinical picture here, but a subject can be born with supra-normal lung func- Background: Spirometry before and after bronchodilator is performed to assess air flow-limitation reversibility. In patients with normal baseline spirometry the frequency of a positive bronchodilator response, as defined by American Thoracic Society/European Respiratory Society criteria, has not been described.
