What it is
COPD is a chronic lung condition with persistent airflow limitation, usually associated with long-term smoke or other inhaled exposures.
Typical presentation
Progressive breathlessness, cough, sputum and repeated exacerbations are common, although symptoms vary.
Assessment
Post-bronchodilator spirometry is needed to establish persistent airflow obstruction.
Treatment approach
Smoking cessation, tailored inhaled bronchodilators, vaccines and pulmonary rehabilitation help reduce burden.
Key safety concern
Severe new breathlessness, confusion, chest pain or blue lips needs urgent assessment.

Overview

COPD is a chronic lung condition with persistent airflow limitation, usually associated with long-term smoke or other inhaled exposures. Emphysema and chronic bronchitis may coexist.

Symptoms and presentation

Progressive breathlessness, cough, sputum and repeated exacerbations are common, although symptoms vary.

CLINICAL FEATURES

Presentation and warning signs

The pattern varies and cannot replace an individual assessment.

Clinical overview
Presentation
  • Progressive breathlessness
  • cough
  • sputum and repeated exacerbations are common
  • although symptoms vary
Clinical assessment
  • Post-bronchodilator spirometry is needed to establish persistent airflow obstruction
  • Interpret results with history and examination
When to seek urgent care
  • Severe new breathlessness, confusion, chest pain or blue lips needs urgent assessment.

Emergency symptoms and clinical severity should be assessed locally.

Clinical assessment and diagnosis

Post-bronchodilator spirometry is needed to establish persistent airflow obstruction. Exposure history and exacerbation risk guide additional evaluation.

ASSESSMENT

How the clinical assessment proceeds

Exact investigations depend on the clinical context.

Clinical workflow
1Define the symptom patternProgressive breathlessness, cough, sputum and repeated exacerbations are common, although symptoms vary.
2Assess disease or alternative causesPost-bronchodilator spirometry is needed to establish persistent airflow obstruction. Exposure history and exacerbation risk guide additional evaluation.
