The ANZSRS also recom-mends that interpretation of spirometry results is based on the lower limit of normal from the reference values and the use of Z-scores where available. investigated the effect of adopting GLI 2012 equations on spirometry interpretation in children and adolescents aged 6–18 years. Testing procedures met the recommendations of the American Thoracic Society (ATS) (Miller, Hankinson, Brusasco el al.

A spirometer measures how much, and how quickly, air can be exhaled in a single blow from full lungs. Spirometry (FEV 1, forced vital capacity [FVC], and FEV 1 /FVC) should be performed in a non‐acute setting before and after bronchodilator administration. @article{Hankinson1999SpirometricRV, title={Spirometric reference values from a sample of the general U.S. For more information, refer to the National Asthma Council Australia's Spirometry Handbook for primary care.
