Study Notes
Lung Volumes and Capacities
- The approximate volume of Tidal Volume (TV) in a healthy individual is around 500 mL.
Total Lung Capacity (TLC)
- TLC represents the maximum amount of air in the lungs, around 6 L.
Expiratory Reserve Volume (ERV)
- ERV represents the additional air that can be forcibly exhaled after normal expiration, around 1 L.
Pulmonary Capacities
- Inspiratory Capacity (IC) includes Tidal Volume (TV) and Inspiratory Reserve Volume (IRV).
- Vital Capacity (VC) includes Expiratory Reserve Volume (ERV), Tidal Volume (TV), and Inspiratory Reserve Volume (IRV).
- Functional Residual Capacity (FRC) includes Residual Volume (RV) and Expiratory Reserve Volume (ERV).
Lung Capacities
- Inspiratory Reserve Volume (IRV) represents the additional air that can be breathed in forcefully after normal inspiration, around 3 L.
- Expiratory Capacity (EC) includes Expiratory Reserve Volume (ERV) and Tidal Volume (TV).
- Vital Capacity (VC) represents the maximum volume of air that can be breathed out after a forced inspiration.
Respiratory Volumes
- Residual Volume (RV) represents the air remaining in the lungs after forced expiration, around 1.2 L.
- Functional Residual Capacity (FRC) represents the air remaining in the lungs after normal expiration, around 2.3 L.
