Normal lung capacity percentage
WebVital 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.In combination … WebThe average total lung capacity of an adult human male is about 6 litres of air.

It's measured by spirometry, a test used to diagnose or monitor lung conditions. The FEV1 measures how much air you can exhale in one second. The FVC measures the total amount of air you can exhale forcefully in one breath.
WebYou will also see another number on the spirometry test results --- the FEV1/ FVC ratio. This number represents the percent of the lung size (FVC) that can be exhaled in one second. For example, if the FEV1 is 4 and the FVC is 5, then the FEV1/ FVC ratio would be 4/5 or 80%. This means the individual can breath out 80% of the inhaled air in the ...
