Total Lung Capacity (TLC)

Total Lung Capacity (TLC) is the maximum amount of air the lungs can hold after taking a deep, full breath. It includes all the air that fills your lungs during normal breathing plus the air remaining after forced exhalation (called residual volume). TLC reflects the overall size and capacity of your lungs, influenced by factors like age, sex, and health. Measuring TLC helps diagnose and monitor lung conditions such as restrictive or obstructive diseases, providing important information about lung function and capacity for effective breathing.
