Breathing Capacity

Meaning

Breathing Capacity refers to the total volume of air the lungs can hold and exchange during maximal inhalation and exhalation, a key indicator of pulmonary function and overall cardiorespiratory fitness. Clinically, this measurement, often assessed via spirometry as Vital Capacity (VC) or Total Lung Capacity (TLG), provides insight into the efficiency of gas exchange and the mechanical health of the respiratory system. Optimal breathing capacity is fundamentally linked to systemic oxygen delivery, which is essential for cellular metabolism and physical endurance.
