Tidal Volume
Volume of air inspired, or expired with each breath (500mL)
Inspiratory reserve volume
Volume of air that can be inhaled above a normal tidal breath (3000mL)
Expiratory reserve volume
Volume of air that can be forcefully exhaled after a normal tidal volume breath (1100mL)
Residual volume
The volume of air that remains in the lungs after a maximal expiration (1200mL)
Inspiratory capacity
Volume of air that a person can inspire beginning at normal end-expiration & maximally expanding the lungs (3500mL).
How is inspiratory capacity calculated?
The sum of tidal volume and inspiratory reserve volume = 3500mL
Functional reserve capacity
Volume or air remaining in the lungs at the end of a normal tidal volume breath. Also at this point the alveolar pressure = atmospheric pressure and there is no gas flow (2300mL)
How is FRC calculated?
It is the sum of expiratory reserve volume and residual volume (2300mL) There is more to it, but just for memorizing volume purposes
Vital capacity
Volume of air that is maximally expired after a maximal inspiration (4600mL) Note: Does not include RV.
How is vital capacity calculated?
It is the sum of the tidal volume, inspiratory reserve volume, and expiratory reserve volume = 4600mL
Total lung capacity
Speaks for itself. Is the maximum volume of air that the lungs can expand to hold on a maximal inspiration (5800mL)
Calculate total lung capacity
The sum of inspiratoy capacity and functional reserve capacity = 5800mL
