Residual volume
Vital capacity is measured using a spirometer. The person takes a deep breath in and then exhales as forcefully and completely as possible into the spirometer. The spirometer records the volume of air exhaled, which is used to calculate the vital capacity.
Forced Vital Capacity (FVC) measures the total amount of air exhaled forcefully after taking a deep breath, usually measured within a specific time frame. Vital Capacity (VC) is the maximum amount of air a person can exhale after a maximum inhalation, regardless of the speed of exhalation. FVC is often used to diagnose lung conditions such as asthma, whereas VC provides a general measure of lung function.
Four factors that can affect the vital capacity of a person are age (vital capacity decreases with age), gender (males tend to have higher vital capacity than females), height (taller individuals usually have higher vital capacity), and physical fitness level (regular exercise can increase vital capacity).

the vital capacity of lungs is 3.5 liters to 4.5 litres
Any lung disease that reduces the forced expiratory volume (FEV) but does not significantly affect the vital capacity is categorized purely as an obstructive lung disease. This is because obstructive lung diseases, such as asthma or chronic obstructive pulmonary disease (COPD), primarily affect the airways by causing obstruction, leading to difficulty in expelling air during breathing out. The vital capacity, which is a measure of the maximum amount of air a person can exhale after taking a deep breath, may not be significantly affected in the early stages of these diseases.
These are equations to calculate reference values for pulmonary function testing. The parameters are for instance TLC (Total lung capacity), VC (vital capacity), FRC (functionnal residual capacity) etc...
vital lung capacity is how much air remains in your lungs after you exhale
The lung volume that represents the total volume of exchangeable air is the vital capacity. It is the maximum amount of air a person can exhale after taking the deepest possible inhalation.
My vital capacity is 1650cc (Yes, it's very low, but I'm twelve and I'm small). cc is used to measure vital capacity.
