Pulmonary Function Testing

The Pulmonary Function Test is performed for the diagnosis and treatment of respiratory disease. It is a simple test that measures air volume and air flow to the lungs.
Who would benefit from testing?

• Patients suffering with neuromuscular disorder, asthma, cystic fibrosis, acute bronchitis, COPD or congestive heart failure.
• Current or former smokers suffering with emphysema.

Why the test is performed?

• Diagnose certain types of lung disease
• Find the cause of shortness of breath
• Measure whether exposure to chemicals at work affects lung function
• Assess the effect of medication
• Measure progress in disease treatment

How the test is performed
• While you are sitting you breathe into a mouthpiece that is connected to an instrument called a spirometer. The spirometer records the amount and the rate of air that you breathe in and out over a period of time. When standing some numbers might be slightly different.
• For some of the test measurements, you can breathe normally and quietly, other tests require forced inhalation or exhalation after a deep breath. Sometimes you will be asked to inhale a different gas or a medicine to see how it changes your test results. This test allows the provider to estimate how well the lungs move oxygen from the air into the bloodstream.
