Spirometry is a test used to determine how well your lungs are working by measuring how fast and how much air you can breathe in and out. This video describes the steps of a spirometry test.

Transcript: Spirometry is a test of how well your lungs are working by measuring how fast and how much air you can breathe in and out. Normally as you breathe in, or inhale, air moves freely through your trachea, or windpipe, then through large tubes called bronchi, smaller tubes called bronchioles, and finally, into tiny sacs called alveoli. Small blood vessels, called capillaries surround your alveoli. Oxygen from the air you breathe passes into your capillaries. Then carbon dioxide from your body passes out of your capillaries into your alveoli. Then you get rid of the carbon dioxide when you breathe out, or exhale. Diseases such as COPD and asthma constrict your bronchials, reducing the amount of air going into your lungs. COPD also damages your alveoli, which may reduce the amount of oxygen in your blood. These diseases can make it hard for you to breathe. Your doctor may recommend a spirometry test to identify a disease in your lungs or check the severity of your existing lung disease. During the test, your caregiver will use a device called a spirometer. A spirometer is a machine that measures exhaled air. Before you take the spirometry test, you will sit in a comfortable chair with your feet flat on the floor. If you have dentures, you may be asked to remove them. For best results, you will be advised to follow your caregivers instructions exactly. To start, you will raise your head and chin so that you can breathe easily. Next, you may place a clip on your nose to prevent air from coming out of your nostrils. Then you'll take a deep breath, filling your lungs completely with air, and hold it. You will place the spirometer's mouthpiece between your teeth and tightly sealed your lips around it. Finally, you will blast the air out of your lungs as hard and as fast as you can be. Your caregiver will tell you when to stop. Adults typically blow for at least six seconds. You will need to perform the spirometry test correctly three times to get accurate results. Your doctor will discuss the results with you and let if you have any breathing problems. more...
