Spirometry is a type of Pulmonary Function Test that measures some lung volumes and flowrates, which can be used to investigate some lung conditions when full Pulmonary Function Testing isn’t needed.
Spirometry is a test that measures the amount of air you breathe in and out. Spirometry is the best test to diagnose asthma and COPD.
Your nose will be clipped and you will breathe in and out through your mouth into a mouthpiece attached to a machine. The respiratory therapist or doctor will instruct you to change your breathing throughout the test. You may also breathe in a tracer gas that will measure the exchange of oxygen and carbon dioxide in your lungs
