- Vital Capacity (VC): Vital capacity is the total usable volume of the lungs which is under voluntary control. This value does not include the entire lung volume as it is not possible to breath all of the air out of the lungs.Total Lung Capacity (TLC): The residual volume (air you cannot expire) + vital capacity (total volume available for use) = total lung capacity.In other words, TLC is the total volume of the lungs!xpiratory Reserve Volume (ERV): This is the difference between the volume of air left in the lung at the conclusion of normal expiration versus at the conclusion of maximal expiration. That means that we have a reserve volume which we can tap into when our tidal volume increases with exercise or activity.

Translations for Vital Capacity Vital capacity. Vital capacity 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. A person's vital capacity can be measured by a wet or regular spirometer. In combination with other physiological measurements, the vital capacity can help make a diagnosis of underlying lung disease. A normal adult has a vital capacity between 3 and 5 litres. A human's vital capacity depends on age, sex, height, weight, and ethnicity. Lung volumes and lung capacities refer to the volume of air associated with different phases of the respiratory cycle. Lung volumes are directly measured, whereas lung capacities are inferred from volumes.

Volume of Human Lungs Inspiration is a movement of air into the lungs, and expiration is a movement of air out of the lungs. Tidal volume is the amount of air taken into the lungs in a single breath. In the average adult, tidal volume is about 0.5 liters. However, the lungs can hold a total of about 4-6 liters, which is close to ten times the tidal volume. This amount is known as the vital capacity.

Lung Capacity and Aging Forced vital capacity: the maximum amount of air you can forcibly exhale from your lungs after fully inhaling. It is about 80 percent of total capacity, or 3.8 liters, because some air remains in your lungs after you exhale. Forced vital capacity can decrease by about 0.2 liters per decade, even for healthy people who have never smoked. Forced expiratory volume (FEV): the amount of air you can exhale with force in one breath. FEV1 is the amount of air you can exhale with force in 1 second.

Forced Expiratory Volume and Forced Vital Capacity - Topic Overview Forced expiratory volume (FEV) measures how much air a person can exhale during a forced breath. The amount of air exhaled may be measured during the first (FEV1), second (FEV2), and/or third seconds (FEV3) of the forced breath. Forced vital capacity (FVC) is the total amount of air exhaled during the FEV test.he amount of air exhaled may be measured during the first (FEV1), second (FEV2), and/or third seconds (FEV3) of the forced breath.
