What is the correct formula for calculating total lung capacity?

Total Lung Capacity = Vital Capacity + Tidal Volume

Total Lung Capacity = Inspiratory Capacity + Expiratory Reserve Volume

Total Lung Capacity = Tidal Volume + Inspiratory Reserve Volume + Expiratory Reserve Volume + Residual Volume

Total Lung Capacity = Tidal Volume + Inspiratory Reserve Volume + Expiratory Reserve Volume

Verified step by step guidance

Understand the concept of Total Lung Capacity (TLC), which is the maximum amount of air the lungs can hold.

Identify the components involved in calculating Total Lung Capacity: Tidal Volume (TV), Inspiratory Reserve Volume (IRV), Expiratory Reserve Volume (ERV), and Residual Volume (RV).

Recognize that Total Lung Capacity is the sum of these four volumes: TLC = TV + IRV + ERV + RV.

Note that Tidal Volume is the amount of air inhaled or exhaled during normal breathing.

Understand that Inspiratory Reserve Volume is the additional air that can be inhaled after a normal inhalation, Expiratory Reserve Volume is the additional air that can be exhaled after a normal exhalation, and Residual Volume is the air remaining in the lungs after a maximal exhalation.
