- Examine for Horner's syndrome - e.g. dilated pupil and drooping of the upper eyelid which may indicate lung cancer.
- Examine for possible causes of postnasal drip - e.g. sinusitis, ear infection, nasal polyps.
- Examine lungs noting breath sounds and their intensity and also the presence of added sounds
- Examine cardiovascular system for evidence of left ventricular failure
- Examine or enlarged liver and spleen - which may suggest a systemic disease involving the lungs e.g. polyarteritis nodosa, sarcoidosis.

- Echocardiogram - may be required to diagnose left ventricular failure.
- Fiberoptic Bronchoscopy with or without lung biopsy - may detect lung cancer, bronchiectasis, foreign body, chronic fibrotic lung disease.
