III. Diagnosis: Pulmonary Function Test Findings

  1. Criteria
    1. FEV1 to FVC Ratio <0.7 (or <LLN or for children<85% of predicted) AND
    2. Normal FVC or FVC response to Bronchodilator
  2. Approach
    1. Assess Severity
      1. See FEV1 interpretation above
    2. Assess Bronchodilator response
      1. Bronchodilator response with FEV1 or FVC increased >12% at any age (or >200 ml in adults)
        1. Consistent with reversible Obstructive Lung Disease (Asthma)
      2. Inadequate Bronchodilator response
        1. Consistent with irreversible Obstructive Lung Disease (COPD)
