Pulmonary Function Testing
We use state-of-the-art spirometry equipment to test lung function. These tests are performed when a patient has difficulty breathing or is chronically coughing. By determining the amount (volume) and/or speed (flow) of air that can be exhaled, we can measure bronchial obstruction. It is used to diagnose asthma or determine the severity of the disease.
To perform the test, the patient is asked to take the deepest breath they can, and then exhale into the device as hard as possible, for as long as possible. Then the patient is asked to rapidly inhale, in particular when assessing possible upper airway obstruction. Then the test is repeated after a bronchodilator treatment to determine if there is an improvement typically seen in asthma.
