  2. What are the techniques and basic interpretations of spirometry?
    • Obstructive
    • FVC - normal or decreased
    • FEV1 - decreased
    • FEF 25-75% - decreased
    • FEV1/ FVC - decreased
    • TLC - normal or increased
    • Restrictive
    • FVC - decreased
    • FEV1 - decreased
    • FEF 25-75% - normal or decreased
    • FEV1/ FVC - normal or increased
    • TLC - decreased
  3. What is obstructive lung disease?
    Obstructive - characterized by limited expiratory airflow, narrowed airways from bronchospasm, inflammation
  4. What is restrictive lung disease?
