This patient is an ex-smoker and has ‘probable’ asthma. He remembers having problems with chest infections and recurrent colds as a child. His father had pulmonary TB and died when he was 7 years old and although he was followed up in TB Clinic for many years he does not remember being diagnosed with TB.
He then worked underground for 35 years and smoked 20 cigarettes per day for 20 years.
Over the last 30 years he has had a productive cough, productive of small amounts of white sputum on a daily basis. Inhaled corticosteroids seem to have relieved these symptoms somewhat. He has a past medical history of eczema, hypothyroidism, hypertension and a TIA associated with loss of vision in his left eye.
What does the spirometry result indicate?
