Spirometry is a test that can help diagnose various lung conditions, most commonly chronic obstructive pulmonary disease (COPD). Spirometry is also used to monitor the severity of some other lung conditions, and their response to treatment. Note: the information below is a general guide only.
The spirometry test is performed using a device called a spirometer, which comes in several different varieties. Most spirometers display the following graphs, called spirograms: 1  a volume-time curve, showing volume (litres) along the Y-axis and time (seconds) along the X-axis.verage values for forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and forced expiratory flow 25â75% (FEF25â75%), according to a study in the United States 2007 of 3,600 subjects aged 4â80 years.
