Definitions for "PULMONARY FUNCTION TESTS"
Keywords:  exhaled, lung, dioxide, pft, oximetry
a series of tests that measure how well air is moving in and out of the lungs and carrying oxygen to the blood stream.
Often called "PFT's". A series of tests done (usually in a lab in a hospital) to determine whether a person has breathing problems, and precisely what those problems are. These are used to differentiate among different diseases and disorders. It is sometimes hard for a doctor to tell just by a regular exam whether a person has asthma or another condition, and pulmonary function tests can help clarify the diagnosis. PFT's do not hurt. They involve things like holding your breath, blowing into a tube as hard as you can, and exercising while wearing a special mask.
A test or series of tests that measure many aspects of lung function and capacity; also referred to as lung function tests.
