Your doctor can get a great deal of information about your lungs and lung function by doing a series of tests called pulmonary function testing. These tests can tell your doctor what quantity of air you breathe with each breath, how efficiently you move air in and out of your lungs, and how well your lungs are delivering oxygen to your bloodstream. |

To learn about your lung health, your doctor may want you to have several pulmonary function tests done including spirometry, lung volumes, diffusing capacity, and arterial blood gases. Most of these breathing tests are done by blowing into a tube while sitting in a chair.
The equipment will be set up for you after being cleaned and disinfected, including a clean mouthpiece. The technologist will tell you what to do before each test. Listen carefully and follow the coaching from the technologist. If you don't understand what to do, ask him or her to tell you in a different way. |
