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.
Spirometry Tests. A spirometry is a functional test of the lungs. Different spirometry tests exist. The main spirometry tests are: 1  FVC (Forced Vital Capacity): the single most important test in spirometry.2  CV (Vital Capacity or Slow Vital Capacity): this test used to be performed to get VC and to be able to calculate the FEV1/VC ratio (FEV1% or Tiffeneau index).VC is a test where a patient needs to expire as hard and fast in the spirometer as possible. The results of the test are compared to the predicted values that are calculated from his age, size, weight, sex and ethnic group.
