Pulmonary Function Test

Lung Function Test

Pulmonary function test (PFT) is an investigation into the various functions of the lungs. This examination aims to assess why certain lung functions are disrupted. Various tests can be performed.


Indication

Examination of the pulmonary function is done if the lung function is impaired. An impaired lung function may be shown as chest tightness and coughing. Diseases which may disrupt the lung function and which may be identified with pulmonary function tests are, for example, asthma and chronic obstructive pulmonary disease (COPD).


Working

With the aid of pulmonary function equipment, the volume of the lungs and the degree of any airway narrowing is measured. During the examination, the patient breaths through a mouthpiece into the pulmonary function device, while the nose is kept closed by means of a clamp.


Procedure

There are several tests that belong to the pulmonary function test. The choice of doing a specific test is depending on the symptoms.

Sometimes, the tests are repeated after administration of a bronchodilator medicine. Pulmonary function test takes about thirty minutes to two hours.
