Clinical Case Study 3

Clinical Case Study in Occupational and Environmental Medicine 

A nurse with persistent cough and wheeze


[e] 

    Her fingers were not clubbed and she was not cyanosed. She did have end-expiratory wheezing.

    Her Peak Expiratory Flow (PEF) is reduced.

    Spirometric lung function tests show that her dynamic lung volumes (FEV1 and FVC) are both lower than predicted for her gender, age, and height, but the FEV1 is more markedly decreased such that the FEV1 / FVC ratio is less than 75% (indeed less than 50% in her particular case). Moreover after inhalation of a Beta agonist there is more than a 15% improvement.

What do the lung function results tell you?

What further lung function tests might you carry out?
