COPD slide share: what the condition means

COPD means chronic obstructive pulmonary disease. It describes long-term airflow limitation involving the airways and sometimes the air sacs of the lungs. A person may develop a persistent cough, bring up phlegm, wheeze, feel chest tightness or become breathless during activity. Symptoms can vary from day to day and may worsen during flare-ups. A symptom page on [Cough](/symptoms/cough/) or [Wheezing](/symptoms/wheezing/) can help you identify what you are experiencing.

A slide presentation can make the condition easier to discuss, but it cannot diagnose COPD. Clinicians combine your history, examination and breathing tests. [Spirometry](/treatments/diagnostics-and-screening/spirometry/) measures how much air you move and how quickly, helping distinguish persistent obstruction from other breathing problems.

Arrange a clinical assessment if ongoing cough, phlegm or breathlessness is affecting work, sleep or walking. Take a list of medicines and describe when symptoms began, what triggers them and whether they change with activity. A [Chronic Disease Review](/treatments/consultations-and-assessment/chronic-disease-review/) can bring symptoms, inhaler technique, vaccinations and an action plan into one review.

If you smoke, support from a [Smoking Cessation Programme](/treatments/lifestyle-and-wellness/smoking-cessation-programme/) can reduce continued airway irritation. Use prescribed inhalers exactly as taught, and ask a clinician to watch your technique if relief is poor.

Seek urgent medical help if breathing becomes suddenly or severely difficult, you cannot speak comfortably because of breathlessness, your lips look blue or grey, you feel confused or unusually drowsy, or prescribed rescue treatment is not helping. A rapid change in phlegm, fever or chest pain also deserves prompt assessment. Do not wait for a slide presentation or routine appointment when symptoms are severe.

Ask whether spirometry is appropriate, what your symptoms suggest, how to recognise a flare-up, and when to use each inhaler. You can also ask how activity, smoke exposure and air quality may affect your breathing.
