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
