Which symptom is a red flag for COPD during exercise?

• A. Severe breathlessness at rest.
• B. Occasional cough with productive sputum.
• C. Mild dizziness.
• D. Stable oxygen saturation.

Answer: (A)

Red flags during COPD exercise testing show when the body is not coping with even small demands, signaling possible acute deterioration. Severe breathlessness at rest is the clearest red flag because it means oxygen and CO2 exchange are being severely compromised without any exertion. That pattern points to an acute COPD exacerbation or another serious problem and can quickly lead to respiratory failure if not addressed promptly. In contrast, an occasional productive cough is a common chronic symptom, mild dizziness can have various non-urgent causes, and stable oxygen saturation during exercise suggests adequate gas exchange—none of which indicate an immediate red flag.
