  2. Lung volumes - Wikipedia

    en.wikipedia.org/wiki/Lung_volumes

    Lung volumes and lung capacities refer to the volume of air in the lungs at different phases of the respiratory cycle. The average total lung capacity of an adult human male is about 6 litres of air. [1] Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath.

  3. Vital capacity - Wikipedia

    en.wikipedia.org/wiki/Vital_capacity

    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). [1] [2] A person's vital capacity can be measured by a wet or regular spirometer.

  4. Minute ventilation - Wikipedia

    en.wikipedia.org/wiki/Minute_ventilation

    Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.) RV

    All aerobic creatures need oxygen ... residual capacity of air, which, in the adult human, has a volume of about 2.5–3.0 liters. [8] During heavy breathing ...

    TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)

  7. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    This is the residual volume (volume of air remaining even after a forced exhalation) of about 1.0–1.5 liters which cannot be measured by spirometry. Volumes that include the residual volume (i.e. functional residual capacity of about 2.5–3.0 liters, and total lung capacity of about 6 liters) can therefore also not be measured by spirometry ...

  9. Lung - Wikipedia

    en.wikipedia.org/wiki/Lung

    The total lung capacity depends on the person's age, height, weight, and sex, and normally ranges between four and six litres. [101] Females tend to have a 20–25% lower capacity than males. Tall people tend to have a larger total lung capacity than shorter people. Smokers have a lower capacity than nonsmokers. Thinner persons tend to have a ...
