Questions: Can you differentiate the obstructive pulmonary disorders? Drag the statements that apply to each into the box. Chronic obstructive pulmonary disease Smoking is a major cause Signs and symptoms include clubbing of the fingers, cyanosis, and pursed-lip breathing Comprised of airway hyperreactivity, emphysema, and chronic pneumonia In emphysema, inflammation, edema, and excess mucus in the airways occurs Alpha 1-antitrypsin deficiency (AAT) increases risk Decreased anterior-posterior chest diameter is a clinical sign Pulmonary function tests are key to diagnosis

Solution Steps

The following statements apply to Chronic Obstructive Pulmonary Disease (COPD):

• Smoking is a major cause.
• Signs and symptoms include clubbing of the fingers, cyanosis, and pursed-lip breathing.
• Pulmonary function tests are key to diagnosis.

The following statements do _not_ apply to COPD:

• Comprised of airway hyperreactivity, emphysema, and chronic pneumonia (This describes Asthma).
• In emphysema, inflammation, edema, and excess mucus in the airways occurs (Inflammation, edema, and excess mucus primarily occur in chronic bronchitis, not emphysema, though both are components of COPD).
• Alpha 1-antitrypsin deficiency (AAT) increases risk (This applies to emphysema, which is a component of COPD, but not necessarily to COPD as a whole. Chronic bronchitis is the other major component of COPD, and is not related to AAT deficiency).
• Decreased anterior-posterior chest diameter is a clinical sign (This is a sign of emphysema, which is a part of COPD, but not all COPD patients have emphysema. This is a more specific sign).
