When to worry about shortness of breath with COPD

COPD can make breathing harder during activity, infections, smoke exposure, or unusually cold air. A flare may bring more breathlessness than your usual level, increased cough, chest tightness, wheezing, or a change in phlegm. New breathlessness can also have another cause, including a heart problem or a blood clot, so do not assume every episode is a COPD flare.

Stop and sit upright, loosen tight clothing, and use your prescribed reliever inhaler exactly as directed. Follow your written COPD action plan if you have one. Avoid smoke and exertion while symptoms settle. Contact your clinician promptly if your usual treatment is not helping, you are needing it more often, or you develop fever or a marked change in sputum.

Call emergency services if you are struggling to speak, breathing is severe at rest, your lips look blue or grey, you become confused or faint, or you have sudden chest pain. Seek same-day medical advice for a clear worsening from baseline, new swelling, or breathlessness that is limiting ordinary tasks. Bring your inhalers and medicine list.

Ask how your baseline breathing should be monitored, when to start your action plan, and whether your inhaler technique is effective. Clarify which symptoms should prompt a same-day call and whether you need a review of vaccinations, triggers, or long-term treatment.
