Pulmonary Function Testing

Pulmonary Function Testing

A pulmonary function test (PFT), also called a lung function test or spirometry, is a simple, noninvasive test to determine how well your lungs are working. The PFT measures your breathing capacity and how fast the air moves in and out of your lungs.  A simple blood test can also measure your oxygen and carbon dioxide levels. The PFT may be used to diagnose shortness of breath or certain lung diseases like Asthma, Emphysema, or COPD.  The PFT is also used to check lung function before surgery.
