What should you know about COPD breathing?

With COPD, air may move less freely through narrowed airways and damaged lung tissue. You may notice breathlessness during activity, wheezing, chest tightness, a persistent cough, or phlegm. Breathlessness can vary from day to day and may worsen with infection, smoke, dust, or exertion. These symptoms can have other causes, so a clinician should assess a new or changing pattern.

[Spirometry](/treatments/diagnostics-and-screening/spirometry/) checks how much and how quickly you breathe air out. It is one part of evaluating COPD and planning care; symptoms and examination also matter.

Use inhalers exactly as prescribed and ask for a demonstration if technique is uncertain. Pace activities, pause before you become exhausted, and sit upright when breathless. Gentle breathing with a longer, relaxed exhalation may reduce the feeling of trapped air for some people. Avoid tobacco smoke and other irritants; a [Smoking Cessation Programme](/treatments/lifestyle-and-wellness/smoking-cessation-programme/) can help if you smoke. A [Chronic Disease Review](/treatments/consultations-and-assessment/chronic-disease-review/) can update your plan.

Call emergency services for severe breathlessness at rest, blue or grey lips, confusion, collapse, or difficulty speaking. Get prompt medical advice if breathing is clearly worse than your usual level, if a reliever is not helping as directed, or if cough, wheeze, phlegm, or fever changes. A sudden change should not be attributed to COPD without assessment.

Ask how to recognise your usual breathing pattern, which inhaler is for quick relief, how to check your technique, and what steps to follow during a flare-up. Ask whether spirometry or a review is needed for new symptoms.
