  1. Expiratory Capacity (EC)- This suggests a total amount of air an adult exhales during a normal breathing process. A summation of expiratory Reserve Volume and Tidal Volume, its formula is EC= ERV+TV. Functional Residual Capacity (FRC) - As the name suggests, it indicates the quantity of air that stay in the lungs after a normal breath
  2. It is an important measure of a person's respiratory health. A decreased vital capacity is an indication of restrictive lung disease where the lungs cannot expand completely. In the case of normal vital capacity, the improper functioning of lungs indicates obstructive lung disease where the lungs are blocked in the airways. VC = TV + ERV + IR
  3. Forced vital capacity (FVC) is the amount of air that can be forcibly exhaled from your lungs after taking the deepest breath possible, as measured by spirometry. This test may help distinguish obstructive lung diseases, such as asthma and COPD, from restrictive lung diseases, such as pulmonary fibrosis and sarcoidosis

Total Lung Capacity. The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE. Forced vital capacity (FVC in % predicted) should be performed annually. It is particularly important to perform the measurement in a sitting and supine position since a difference of > 20% between the sitting and supine FVC indicates diaphragmatic weakness and is a predictor of nocturnal hypoventilation ( Wallgrin-Pettersson et al., 2004; Mellies et al., 2005 )

Spirometry Tests. A spirometry is a functional test of the lungs. Different spirometry tests exist. The main spirometry tests are: FVC (Forced Vital Capacity): the single most important test in spirometry.; 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) How big you can blow up a balloon to be has to do with something called your 'vital lung capacity.' This is basically how much air your lungs can push out in one breath.
