Obstructive vs. Restrictive Pulmonary Disease

Question 1

Disease characterized by airflow limitation
that is not fully reversible

Airflow limitation is usually both progressive & associated with abnormal inflammation response of lungs to noxious particles & gases

Answer 1

Obstructive Pulmonary Disease

Question 2

Restrictive disease due to alterations in lung parenchyma & pleura. Difficulty expanding lungs caused by a reduction in lung volumes

Fibrotic changes within pulmonary parenchyma or pleura due to idiopathic pulmonary fibrosis, asbestos, radiation, oxygen toxicity

Answer 2

Restrictive Pulmonary Disease

Question 3

Chest X-ray Findings:

Hyperinflation
Flattened diaphragms
Hyperlucency

Answer 3

Obstructive Pulmonary Disease

Question 4

Chest X-ray Findings:

Reduced lung volumes
Diffused interstitial infiltrates
Pleural thickening
Atelectasis (in alterations in chest wall)

Answer 4

Restrictive Pulmonary Disease

Question 5

Lung Volumes

Decreased vital capacity
Increased residual volume & functional residual capacity

Answer 5

Obstructive Pulmonary Disease

Question 6

Lung Volumes

Decreased vital capacity, residual volume, and FRC

Answer 6

Restrictive Pulmonary Disease
