These tests help to measure the lungs’ ability to move air in and out of your lungs.
The tests are often done with special machines that you breathe into. They may
Spirometry. This test uses a spirometer device to see how well your lungs
are working. It is one of the simplest, most common pulmonary function tests. It may
be used for any or all of these reasons:
- To find out how well your lungs take in, hold, and move air
- To keep watch on a lung disease
- To see how well treatment is working
- To find out how serious your lung disease is
find out if your lung disease is restrictive or obstructive. Restrictive means
less air will get into your lungs. Obstructive means less air will get out of your
flow monitor. This test measures the fastest speed you can blow air out of
your lungs. Inflammation and mucus in the large airways in the lungs narrow the
airways. This slows the speed of air leaving the lungs. It can be measured with a
peak flow monitor. This measurement is very important in telling how well your
disease is being controlled.
