What does dyspnea indicate in a COPD patient?

• A. It indicates improvement in breathing
• B. It occurs only during sleep
• C. It indicates difficulty breathing, which may be present at rest or with exertion, and becomes progressive over time
• D. It indicates no change in symptoms

Answer: (C)

Dyspnea in COPD shows that breathing is becoming more difficult, and it often signals progression of the disease. In COPD, airflow limitation and air trapping lead to increased work of breathing and reduced ventilatory reserve. As the condition advances, the sensation of shortness of breath can occur at rest or with less and less activity, and episodes tend to become more frequent or severe. This makes dyspnea a marker of worsening symptoms rather than improvement, and it is not limited to nighttime—the breathlessness can happen at any time. A change in dyspnea prompts reassessment and possible adjustments to therapy, and may indicate the need to evaluate for exacerbations, optimize medications, and consider oxygen if resting hypoxemia is present.
