title: 'pft: Pulmonary Function Test Interpretation per ERS/ATS 2022'
version: 1.0.1
abstract: Computes predicted values and lower/upper limits of normal for pulmonary
  function tests according to American Thoracic Society ('ATS') and European Respiratory
  Society ('ERS') reference standards. Supports spirometry (Global Lung Function Initiative

  static lung volumes ('GLI' 2021, Hall et al. (2021) <https://doi.org/10.1183/13993003.00289-2020>),

  author correction <https://doi.org/10.1183/13993003.50010-2017>). Also assigns interpretive
  pattern labels (Normal, Non-specific, Obstructed, Restricted, Mixed) from spirometry
  and lung-volume measurements following the 'ERS'/'ATS' 2022 interpretation algorithm,
