emphysema
Start with the big picture
Emphysema is associated with cigarette smoking, biomass exposure, and inherited α1-antitrypsin deficiency. Typical features include progressive exertional dyspnea, little productive cough, hyperinflation, quiet breath sounds, and hyperresonance; imaging may show a flattened diaphragm or bullae. Diagnosis is supported by post-bronchodilator spirometry showing an FEV1/FVC ratio below 0.70. Care combines smoking cessation and preventive measures with symptom-guided inhaled medicines, pulmonary rehabilitation, and attention to nutrition and respiratory irritants. Selected patients may benefit from long-term oxygen or α1-antitrypsin infusions. Follow-up includes checking inhaler technique and adherence, lung function, weight, and exacerbations. The full lesson develops these principles and their clinical criteria in greater detail.
