MODEL RELEASED: Pulmonary function in cystic fibrosis. A physiotherapist performing a lung function test on a patient using a Vitalograph. This device measures various aspects of lung function such as the vital capacity, forced vital capacity and forced expiratory rate. The age, height and sex of the patient is entered into the computer, which calculates the theoretical values for the test. The device then displays the patient's performance as a percentage of the theoretical value. Cystic fibrosis is a hereditary disease affecting the exocrine glands. This may lead to thick mucus obstructing the bronchi with severe infections being a common complication.
