Total Lung Capacity

Total Lung Capacity (TLC) is the maximum amount of air that your lungs can hold after taking the deepest breath possible. It includes all the air in your lungs: the air you breathe in normally, plus the additional air added during deep breathing, and the air remaining after you exhale completely. Think of it as the full capacity of your lungs, reflecting their size and health. TLC is important for understanding lung function and detecting potential respiratory issues, such as restrictive or obstructive diseases.
