Question
6 out of 11
 

Polycythemia occurs in ? (LQ)



A Chronic bronchitis
B Emphysema

C Both
D None

Ans. A

Chronic bronchitis

Complication:

1). Acute exacerbations

2). PolycythemiaQ (In ch bronchitis)

3). Respiratory failure

4). Cor pulmonale Q

5). Pneumothorax (ruptured bullae Q) (In emphysema)

6). Pulmonary artery hypertension Q (In ch bronchitis)

Pulmonary Hypertension in COPD has been attributed to multiple factors including:

1). Hypoxia

2). Acidemia

3). Pulmonary vasoconstriction (secondary to hypoxia)

4). Hypercapnia

Mechanical effect of high lung volume of emphysema on pulmonary vessels

1). Loss of small vessels in vascular bed

2). Regions of emphysematous lung destruction

Extra Edge:

Lung function: obstructive + air trapping (FEV1 <80% of predicted, FEV1 / FVC ratio <0.7%.
