Pulmonary Function Tests are available at the Northeast Georgia Diagnostic Clinic for patients with asthma, emphysema and a variety of lung disorders.
While physical examinations tell your physician how your lungs sound and x-rays tell your physician how your lungs look, Pulmonary Function Tests tell your physician how your lungs perform.
PFTs are performed to:
- Diagnose lung diseases.
- Help determine the cause of breathing problems.
- Moniter response to treatment of a variety of lung disorders.
- Identify people at high risk for lung disease.
- Evaluate the ability of a patient with lung disease to tolerate surgery.
- Monitor the lung function of a person regularly exposed to substances that can damage the lungs.
Pulmonary Function Tests are easy to perform. For most PFTs, you will wear a nose clip to make sure no air passes in or out of your nose during the test. You will breathe into a mouthpiece attached to a recording device. You may be asked to breathe rapidly or normally, or to exhale and inhale deeply and forcibly.
How to Prepare
