Study Notes
Obstructive Pulmonary Diseases: COPD and Asthma
- Emphysema leads to loss of elastic tissue from alveolar walls
- COPD symptomatic presentation includes dyspnea, weight loss, barrel-chested appearance, breathing through pursed lips, prolonged expiration, wheezing, and cough
- Chronic bronchitis is defined by excessive mucus production in the bronchial tree and is mainly caused by cigarette smoking
- Pathogenesis of chronic bronchitis involves lumen occlusion, inflammation, airway wall thickening, fibrosis, and decreased ciliary function
- Chronic bronchitis patient presentation includes dyspnea, frequent cough and sputum, substantial drop in PaO2, and increased PaCO2
- Asthma is a disorder of the conducting airways caused by immunological reactions, leading to episodic bronchoconstriction
- Asthma triggers include respiratory infections, irritants, cold air, exercise, and stress
- Asthma types include atopic, non-atopic, drug-induced, and occupational
- Atopic asthma is triggered by allergens and diagnosed through skin tests and increased IgE levels
- Non-atopic asthma is triggered by infections, smoking, and air pollutants, and has negative skin test results and no increase in serum IgE
- Drug-induced asthma is caused by aspirin and affects about 10% of asthma patients
- Occupational asthma is triggered by fumes, dusts, and chemicals, diagnosed through decreased FEV1/FVC, and treated by allergen avoidance, beta-adrenergic agents, and glucocorticoids
