Do you have a history of smoking or exposure to secondhand smoke or environmental/occupational pollutants? Do you have a family history of chronic lung disease? Do you have symptoms of coughing, wheezing, and/or shortness of breath? If you answered yes to all three questions, then you are a candidate for spirometry testing.
Spirometry is a test that can help diagnose various lung conditions, such as asthma, bronchitis, and emphysema. The test is performed using a handheld device known as a spirometer, which measures the volume of air inspired and expired by the lungs. There are two types of spirometers, namely: (1) the volume displacement spirometers (the earlier version) and (2) the flow-sensing spirometers (the modern version).
