Obstructive vs. Restrictive Lung disease

  1. 1. RESTRICTIVE VS. OBSTRUCTIVE LUNG DISEASES Fatima AlAwadh
  2. 2. INTRODUCTION LUNG VOLUMES AND CAPACITIES 2.5 L 0.5 L 1.5 L 1.5 L Inspiratory Reserve Volume Tidal Volume Residual Volume Expiratory Reserve Volume Inspiratory Capacity Functional Residual Capacity Vital Capacity Total Lung Capacity
  3. 3. 2.5 L 0.5 L 1.5 L 1.5 L OBSTRUCTIVE Normal Obstructive Forced Vital Capacity N or Forced Expiratory Volume in 1sec Total Lung Capacity N or Residual Volume FEV1 / FVC
  4. 4. RESTRICTIVE Normal Restrictive Forced Expiratory Volume in 1sec N or FEV1 / FVC N or Residual Volume Forced Vital Capacity Total Lung Capacity
  5. 5. OBSTRUCTIVE VS. RESTRICTIVE Obstructive disorders: Obstructive disorders are characterized by a reduction in airflow, particularly the FEV1 and the FEV1/FVC. Restrictive disorders: Restrictive disorders are characterized by a reduction in lung volume, specifically a TLC < 80% of the predicted value.
