Obstructive Vs Restrictive Lung disease

Obstructive lung disease

  • TLC – Increased
  • RV-Increased
  • VC- Decreased
  • FEV1/FVC- Decreased

  2. Asthma
  3. Chronic Bronchitis
  4. Bronchiectasis
  5. Emphysema
  6. Cystic fibrosis

Restrictive Lung disease

  • TLC – Decreased
  • RV- Decreased
  • VC- Decreased
  • FEV1/FVC- Increased

Examples

  1. Sarcoidosis
  2. Idiopathic Pulmonary Fibrosis
  3. Pneumoconiosis
  4. Diaphragmatic Weakness
  5. GBS
  6. Obesity
  7. Kyphoscoliosis

Restrictive Lung disease types

  • Pulmonary parenchymal
  • Extraparenchymal(Inspiratory) -Myasthenia
  • Extraparenchymal(INSP+EXP) – eg:Chest wall abnormality(Kyphoscoliosis)

RV is high in Kyphoscoliosis.
