Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume. It is approximately equal to Forced Vital Capacity (FVC). A person's vital capacity can be measured by a wet or regular spirometer.
Learn about the terms related to lung volume and lung capacity such as vital capacity, tidal volume, inspiratory capacity, etc. Find out how to measure the lung capacities of different animals and humans with a spirometer.
Jul 24, 2023 · Vital capacity (VC) refers to the maximal volume of air that can be expired following maximum inspiration. It is the total of tidal volume, inspiratory reserve volume, and expiratory reserve volume (VC = V + IRV + ERV). Vital capacity may be measured as inspiratory vital capacity (IVC), slow vital capacity (SVC), or forced vital capacity (FVC).

Feb 12, 2017 · Vital capacity is the amount of air that the lungs can expel after having been filled completely. The vital capacity represents the change in volume from completely emptied lungs to completely filled lungs.
Mar 22, 2024 · Spirometry is a test that measures how much air you can breathe in and out in one second and in total. It can help diagnose lung diseases such as COPD and asthma. Learn how to prepare, what to expect, and how to interpret the results.
Jan 17, 2023 · Vital capacity (VC) is the maximum amount of air that a person can exhale after inhaling as much air as possible. It is also the sum of tidal volume and the inspiratory and expiratory reserve volumes, which capture the differences between normal breathing and maximal breathing.
