Lung Function Tests & Breathing Evaluations
Lung function tests include breathing tests and tests that measure the
oxygen level in your blood.
The breathing tests most often used are:
Spirometry: This test measures how much air you can breathe in and out. It also measures
how fast you can blow air out.
Body plethysmography: This test measures how much air is present in your lungs when you take
a deep breath. It also measures how much air remains in your lungs after
you breathe out fully.
Lung diffusion capacity: This test measures how well oxygen passes from your lungs to your bloodstream.
These tests may not show what's causing breathing problems, however,
they can show when they are present. You may be required to take other
tests as well, such as an exercise stress test. This test measures how
well your lungs and heart work while you exercise on a treadmill or bicycle.
Two other tests that measure the oxygen level in your blood are pulse oximetry
and arterial blood gas tests. These tests are also called blood oxygen
tests. Pulse oximetry measures your blood oxygen level using a special
light. For an arterial blood gas test, your doctor takes a sample of your
blood, usually from an artery in your wrist. The sample is sent to a laboratory,
where its oxygen level is measured.
