Lung volumes and vital capacity - Cardio-respiratory system

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 … Se mer The vital capacity can be used to help differentiate causes of lung disease. In restrictive lung disease the vital capacity is decreased. In obstructive lung disease it is usually normal or only slightly decreased.

NettetInspiratory capacity is recruited thanks to stable TLC and pre-exercise end-expiratory lung volume reduction. Because ERV is reduced, end-expiratory lung volume does not further decrease during exercise to avoid the mechanical disadvantage of the lower portion of the pressure–volume curve of the respiratory system.
